I have just enrolled in a Data Science course on Udemy  and I learned good stuff.

Today, I’ll show you how to install Tableau.

Use your web browser to go to https://www.tableau.com/ . On the homepage, there are several options of packages to be installed.

For the course that I do, there is the choice between 2 versions : Tableau Desktop and Tableau Public.

Tableau Public charged and of course, there is a trial version of 14 days. Tableau Public is free and is perfectly usable for this course because there are the same features as Tableau Desktop.

Install Tableau Desktop

Click on the « Try Now » button on the top right

Here there are 3 options : Tableau Desktop, Tableau Online and Tableau Server. What interests us is Tableau Desktop and for that we need to give an email. Once you gave your email, the installation file downloaded automatically.

tableau desktop public data visualization

Don’t worry, the download contains the correct version of the file. This will be a « xzy.EXE » file for Windows and a « xyz.DMG » file for Mac.

If this isn’t the right version that has been downloaded, you can always do this manually with these links.

As soon as the download is complete, you can watch tutorial videos in the « Get Started » area. It’s simple and intuitive.

Install Tableau Public

To install Tableau Public, it’s a little different because you have to go to another website. Use your web browser to go to https://public.tableau.com/s/.

Like for Tableau Desktop, you need to give an email to install the installation file automatically.

The majority of people who use Tableau Public are journalists or public organizations that do not have confidential data because Tableau Public data is on public servers. And as you know, data of a public server is freely accessible to everyone on internet.

Here the Tableau Public main graphic user interface.

tableau desktop public data visualization

Tableau Desktop and Tableau Public have the same structure, features and visualization layout.

But there are 3 differences :

  • With Tableau Public, you can’t extract data because your data is on a public server.

  • With Tableau Public, you need to make screenshots (printscreen) of your charts because you can’t export them.

  • With Tableau Desktop, you can connect to more file type and you can export your charts.

Know How Much Weight To Lift (Part 1)

how much

I read a Nerd Fitness article  and I learned good stuff.

When we’re beginners and we have studied the theory well, the first time we train in a gym, we have this kind of questions :

  • What weight should lift to begin with ?

  • If my program tells me to do 5 sets of 5 reps at 80 % of my 1 rep max, how do I get to know my 1 rep max ?

  • In my program, there isn’t this notion of percentage and 1 rep max, how do I know the weight I have to lift ?

Here are some tips to start your program with the right amount of weight.

Bodyweight

bodyweight exercice

The fist step of your workout is to do bodyweight exercices to learn how to do well the bench press.

This may sound odd but I really advise you to take your time to learn to perform well without weights or with a very light weight. Imagine that you can’t climb stairs normally, What happens when you have to climb stairs with bags of supermarket ? Yes, you’re going to hurt yourself.

Here is how you can learn a movement without barbell, dumbbells and weights :

  • To learn barbell’s movement without barbell, you can take a broom stick or a PVC pipe.

  • To learn dumbbells movement without dumbbells, you can take 2 sections of PVC pipe or 2 bottes of water.

It’s true that it’s not the same sensations that with weights but it allows you to learn a movement without risk to hurting you.

With this method, you can train at home alone. No one looks at you like in a gym so you’re less nervous. What’s cool is that yo can film yourself with your smartphone to compare your videos with tutorial videos that you can find on Youtube of elsewhere.

To learn in depth how to move, I recommend the book Starting Strength .

Once you feel confortable with movements, you go to the next level.

Barbell

barbell

For your first training with the barbell for the bench press, you’ll use the barbell without weights to be comfortable with. As you read in my articles Back To The Source Of Equipment Part 1 et Part 2 , the barbell i’m talking about is the Olympic barbell 20 kg (45 lbs).

If you have difficulty with the Olympic barbell, here are some alternative.

A lighter barbell

Look in your gym if there are lighter barbell like the « women’s bar » 13.6-15.87 kg (30-35 lbs) or the « training bar » 6.8 kg(15 lbs). EZ curl bar isn’t designed for the bench press.

Dumbbells

You can use dumbbells. It’s true that isn’t really the same movement but it will help you to build your strength to be comfortable with the Olympic barbell.

Bodyweight exercices

Continue to do bodyweight exercice as squat, lunges, pull ups, push ups. This will help you to build your strength to be comfortable with the Olympic barbell.

That may be the opposite. For you to use the Olympic barbell without weight is easy. I still advise you to continue your first training with the Olympic barbell without weight. In this way, you can concentrate for each repetition to have the best technique possible. Wait the next session to add weights.

There isn’t ego in a gym. Unfortunately in gyms we often see people lifting very heavy weights with a poor technique and this happens more and more often. I have 2 friends who have dislocated their shoulders with the bench press and now they can no longer develop their chest and their shoulders.

One of these 2 friends showed in front of me who his shoulder dislocates when he do bench press and he regrets a lot of having lift too heavy with a bad technique. Since I’ve seen this, I prefer to lift lighter with a good technique and I advise you to do the same.

If after your first training with the Olympic barbell, you’re still not comfortable with. I recommend you to continue to train with the Olympic barbell without weights until you’re comfortable with. If you need to do this for 10 sessions, do it, there is not problem.

I’ll tell you something, Listen carefully. If you get hurt, it’s not because you body isn’t ready. It’s because you don’t trust in you under the Olympic barbell. Self-confidence is the most important element to lift heavyweights and heavier. It means knowing when you can lift and when you can’t lift. An athlete train his/her body and mind.

If you have planned to use dumbbells as your main lift (like me) and don’t use Olympic barbell, stat with 2.2-4.5 kg (5-10 lbs) dumbbells to work your technique.

Add weights

weight plate

Most beginners workout programs are 5 sets of 5 reps, 3 sets of 8 reps or 3 sets of 10 reps. For this example, we’ll use 5 sets of 5 reps.

Your workout should always begin with a warm-up routine. Then you take the barbell without weights and you do the repetitions number of your program (for our example, it’s 5).

Yeah, yeah, I know. You thought that after the warm-up routine, you could lift heavy but you have not quite prepared your body yet. For each exercice, you need to warm your body with lightweights. It’s very important to do this because it allows your body to warm your nervous system and the muscles needed to make the movement.

For beginners, it’s really important to learn the good technique right away.

Increase gradually

Once your nervous system and your muscles are ready, add between 1.1 kg (2.5 lbs) and 4.5 kg (10 lbs) on each side. Do a set of 5 reps with this weight.

Note : If your strength training is based on dumbbells like me, starts with 2.2 kg (5 lbs) dumbbells, then 4.5 kg (10 lbs) dumbbells for example.

If you can do 5 reps without degrading your technique and without slowing the speed of the barbell, you can add weight. If it’s really light adds 4.5 kg (10 lbs) on each side or less like 2.2 kg (5 lbs).

Continue to do this process until the speed of the barbell or you technique begins to deteriorate. The weight you lifted before your technique deteriorates is the starting weight on which you will base all your future exercises.

The basic weight for your workout

If you thought you could lift more, don’t panic, that’s the right number. You’re not in a gym to impress someone. It doesn’t matter if it’s your first or your 1000th workouts. It’s better to start too light than too heavy. The goal is to do quick reps with a good technique. When your technique deteriorates, you have reached a limit with your body, too much will create an injury.

In this process, you’re trying to lift the heaviest weight you can so use collars for your safety. When it becomes difficult, ask someone to be your spotter to avoid an injury.

This is the end of the Part 1. In the Part 2, I’ll talk about what to do after several workouts, find your 1 rep max and what amount of weight is respectable to lift.

From Beginner To Become Your Own Personal Trainer (Part 2)

I read a Nerd Fitness article  and I learned good stuff.

Mastering the movement

mastering the movement

If you want to have lasting results, there is no shortcut, you need to learn the basic movements. It’s like at school, learning and progressing.

The best way to start a strength training is to do a bodyweight workout at home (I started like that). If you want to do a barbell movement in your workout, you can use a broom stick or a PVC pipe. If you want to do a dumbbell movement, you can use 2 sections of PVC or 2 bottles of water.

The technique is very important for movement like squat, deadlift, pull ups, bench press. That’s why using light weight will allow you to learn to make the right movements. It’s going to be a bit long but you’re going to avoid having injuries and months of frustration.

Use your smartphone to make videos of your exercices to compare them with tutorial videos that you can find on Youtube or others.

It’s possible that you feel uncomfortable with an exercice even if you have videos to improve. In this case, I advise you to see gyms in your area to hire a coach for 1-2 sessions. It’s only to improve your techniques, it’s not to hire a coach for several months. This coach will teach you what you need to know to train at home safely.

It’s not always obvious to understand tutorial videos on Youtube or others. The reason is that the person who explains how to do the technique knows very well how to make the movement but forgot to explain mistakes he/she made when he/she was a beginner.

If you have difficulties with a part of the movement, don’t get upset or be frustrated. It’s just something you can improve and by tracking your workouts, you’ll see that.

What to take

what to take

Clothes

To start, takes comfortable clothes. Don’t buy special fitness clothes. The gym isn’t a fashion show, forget what people think about you. There is no ego in a gym. I like to wear simple clothes, no known brand because I always tear my clothes by dint of using them. Maybe I dress like a tramp but everyone is silent when they see my performances.

Note : If you go to workout after school/work, take your gym outfits with you to go to the gym directly.

Shoes

For shoes, takes shoes minimizes with a flat and hard sole. For example Classic Chuck Taylor , Vibram or Powerlifter shoes .

I use for my strength training Classic Chuck Taylor and for my cardio Puma.

Drink

Take a bottle of water. It’s handy to have a bottle of water next to you to drink between 2 sets rather than go to the toilettes.

Notebook

Takes a notebook to track your workout during your workout. Often after our workout we don’t remember the workout’s details as having done 1 more rep or 1 more set. If you use a smartphone, you can use Evernote  as a notebook or a fitness app like Jetfit .

Shower gel

We sweat during our workout and it’s always nice to take a shower after an effort. If you’re going to train before going to school/work, shower gel is essential.

Your music

Takes an MP3 player or smartphone with a great playlist to « get in the zone » and make you feel like a superhero. Often music in gyms are special. In my gym often we can hear bachata or it’s nightclub ambiance.

My playlist it’s 50 Cent, G-Unit, 2 Eminem’s song and soundtrack of japanese cartoon « Hajime No Ippo » (boxe) and « Hokuto No Ken » (martial art) and soundtrack of « Rocky ».

I’ve been using my smartphone for a few years to listen to my music and keep track of workout (Jefit) and it’s really cool.

The basic rules

basic rules

There are basic rules for gyms. By following these rules, you’ll be comfortable in any gym :

  • Put weights in the right place when you finished using them.

  • If a person is using a equipment you want to use, it’s OK to kindly ask this person how many sets he/sh has left to do.

  • If another person wants to use the same equipment as you, you can offer him/her to work together. You do a set while the other rest and vice versa. You may not be comfortable with that and you can say no. Say something like « no but I still have 2 sets and after it’s for you ».

  • If a person asks you to spot and you have never done that, tell that person you never did that and ask him/her what you’d like you to do. This person will explain everything to you.

  • If a person offer to spot you on an exercice (bench press), don’t worry. Usually it’s always an experienced person who does this to help you. It’s motivating and it’s a good opportunity to exceed your limits.

  • Cleans the sweat that has on the equipment you want to use. In gyms, there is always a station with liquid cleanser and tissues.

  • With benches, leaves a space between you and the others so that everyone can keep their personal space.

  • Even if you see a person making a move that you have never seen, let it happen. You don’t want someone to come and tell you that what you do is wrong. It’s the same for others.

  • Avoid speaking in your smartphone and call the person after your workout. You’re in a gym to train, only to train.

  • Don’t sit on equipment forever. Do your sets and go to the next exercice. Don’t sit on equipment for 2 hours.

Start your strength training as soon as possible. It’s by doing exercices several times that you’ll improve your technique. Don’t be afraid to do wrong because the majority of people in a gym have no idea what they’re doing. I have been practicing for several years and I’m always improving each one of my exercices, I say each of my exercices.

What keeps you from starting a strength training ?

The Mistake Of Learning From Mistakes

mistake

I watched an Olivier Roland’s video  and I learned good stuff.

It’s true that learn from your mistakes is a good method to improve yourself but you can do a huge mistake by doing this. Let me explain to you, the huge mistake is to only learn from your own mistakes. Look the world, we’re billions and there are billions of people who lives before us. As everyone makes mistakes, learning from mistakes of others is also a good strategy.

Mistakes of others

mistake others

Look mistakes from people who are in the domain where you want progress allow you to save time and money. I think we know it but we forget to do it quickly. It’s important to have a strategy to learn from mistakes of others to progress.

I tell you the truth, I also made this mistake several times. Sometimes I noticed that I had a talent and I was alone in solo thinking that I was smart enough to succeed. I thought I didn’t need professors, books, etc. It’s an ego trip, it’s the best method to waste time and almost guarantee failure. Yes, I know there are exceptions, some people happen to be successful in being solitary wolves but it’s clear that they lose a lot of time.

No matter where you want to succeed, there is a golden rule. You need master the basics ! Once you master the basics, you can be creative but not before.

You can try to be creative before master the basics and in 90 % of the cases you’ll fail, it’s true. Look at people who are successful, people who are creative, they were all newbies and they all learned the basics.

Example

Looks at the creative chefs who have restaurants with 3 stars in the Michelin guide. Do you think at the first day in kitchen, they said to themselves : « Go, I make a crazy recipe ? ». No, they learned to cook rice, pasta and they had to learn the basics like everyone else.

There is a company very creative that is Cirque Du Soleil  that reinvented the show. You notice that there is a lot of circus inspiration and other domains. It looks very similar to fusion restaurants. You know this concept where you take the best recipes from 2 countries and you make a mix of 2 to make a menu.

Learn form mistakes of others

biography

First

The simplest method is to read the biography from people who are successful in the field where you evolve. You’ll learn a lot of things, you’ll see that they strarted from nothing and sometimes they made incredible mistakes. Reading biographies helps you avoid making these mistakes.

Second

Be in touch with people who are successful in your field. Don’t absolutely look for people who are at the level where you would like to be, communicate with people who are better than you. Ask them what are the classic mistakes that beginners make.

Put in place a stratregy to know mistakes of others and solutions they used to move forward. You’ll see, this will save you from unnecessary stress.

Attention is a thing to do in addition to attend trainings, see tutorials in video,etc.

What I mean is not be a lone wolf. Connect you, inform you, be curious, attends trainings and find mistakes that you must not make before you make them.

Sometimes We Are Struggling To Be Healthy

struggling to be healthy

I read a Nerd Fitness article  and there is good stuff.

Doing things we know we need to do may sometimes seem impossible. We know we can have a better lifestyle to « stay motivated » and « get focused ». And yet when we work on a long-term project, we have the impression of always starting from scratch.

We doubt : « What’s happening ? Why I can’t do it anymore ? »

  • I know I need to eat better

    But after cook healthy meals for one week, I don’t have the time to cook and I buy pre-prepared meals.

  • I know I need to train more often

    But after train for one week, I’m less motivated, I see no result and I’m demoralised.

  • I still have a good physique

    But I try to have an athletic body like the pros but it’s always frustrating.

I already tought about it and I think you too. Change this situation can be useless if we aren’t well prepared. It’s like a video game when you will fight a Boss with 50 % of your life without potions.

Boost your inventary

inventory video game

It’s real, I advise to everybody to prepare their meal of the day in advance (like my Instagram’s video) to have health meals. And I advise you to eat 1-3 time per week in a restaurant (see tips for eating at restaurant and staying healthy).

There is the perfect plan and the realistic plan. We like prepared perfect plans to reach our goals but in reality, it’s harder. An imperfect plan executed is better than a perfect plan poorly executed.

  • Potion

    You can go in a restaurant to eat a big plate of rice, protein and vegetables. It’s quickly prepared, it’s not expensive and you have healthy foods in your body.

  • Improve weapons

    Find a blender with a good motor to do fruits/vegetables shakes. It’s perfect for a snack at 16h (4pm).

  • Improve your armor

    Buy a rice cooker to save your time in evening.

These elements help you to reach more easily your daily calories goal. I have never plan my meals for all the year, I plan what I will eat each week (when I go to the supermarket) and each day, I do my best to eat as healthily as possible despite the unexpected. It’s this imperfect plan that I use and I see results ! If I had continued to follow my perfect plan, I think I would have given up because of my environment.

Now, when I see old friends they’re surprised to see how my physique changed better and there are some who jealous me (but there is less brawl than before, it’s cool).

In a video game, when you will fight against a new Boss, you will have the maximum of potions to have the maximum chance of winning. When you attack a new problem in your life, adjust your priorities to build a new habit or miss your attempt to be healthy.

Mercenary and strategy guide

mercenary

In a video game, you can have mercenaries to help you to fight the Boss and you can unlocked strategies can help you have the advantage.

You used strategy guides or tutarial video to help you to beat a difficult Boss. Some people say it’s « cheat » but it’s up to you to follow instructions and execute them properly for it to work.

In life, you can also have mercernaries and strategy guides. You can find tutorials like « How to do squat properly » or « How to create your workout plan » but often it’s our lack of knowledge or lack of confidence that keeps us from succeeding.

Have a great mercenary (personal trainer) to reach your goal who all times yelling, prodding, educating and helping you to have results. Just have somebody to help you for one session or for one week can do the difference between long term success and long term frustration.

That means you need to have a mercenary (personal trainer) forever ? No, but it’s good to have the opportunity for several months to learn from a great mercenary (personal trainer) to follow the patterns set out in a strategy guide to have confidence to attack the Boss without being assisted.

A victory is a victory

victory

When you try to fight the Boss, all that matter is that you have 1 % of life when the Boss has 0 %. This can be an ungly fight and even you used 10 potions, this victory is important to continue. It’s for this reason you buy potions and upgrade your armor. This is what make the difference between victory and throw your controller against the wall.

The life is the same and it’s important to organize priorities to have success :

  • Discuss with your family about the financial investment to have a better health (gym, mercenary)

  • Save money to by health product and have tools necessary to avoid to eat at restaurants everydays.

Organize your priorities to reach your fitness goals and others aspects of your life, right now. There are Bosses that you fight with 50 % of your life ?

  • Hard to meditate everydays ?

    Use calm.com  and follow the 2 minutes of meditation guide (strategy guide).

  • Hard to start yoga ?

    Subscibe to a yoga class for a month to learn movements. By this way, you will have more confident to do yoga at home (mercenary).

  • Hard to eat better ?

    Seek in Craiglist or another website that do the same thing and find a Chef to prepare meals for you at a reasonable price for a month (improve inventory)

  • Hard to walk more ?

    Buy a Fitbit and train you body to walk 10 000 step each day until you can do it without technological assistance (improve armor).

  • Hard to do squat and deadlift properly ?

    Hire a personal trainer to learn properly to do squat and deadlift. Contact this personal trainer one month later to check your technique (mercenary).

  • Hard to learn a new language ?

    Use iTalki.com  and speak with a native speaker and in exchange you learn to him/her your native language. (improve your group).

Yes, it’s possible. You will try several times and you will do several mistakes to improve yourself and it will be difficult. The most important is to know why you do all these things and not the others. It’s to improve your lifestyle and you’re the only person to do it.

What is the Boss you’re fighting and what mercenary, armor, potion, you use to build this new habit to beat it ?
