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.

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 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.

Have A Lot Of Ideas For Articles Or Videos

ideas

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

Here is an idea for having several ideas to create articles and videos. This idea is to write a book of at least 50 pages.

The concept is to share regularly with your audience your reflections and the development of your book.

While you’re writing your book, you’re going to learn new things because you really want your book to help people. It’s for this reason that you show your book’s content before your publishing it.

Maybe for you it’s something stupid because your audience can read your book’s content for free but here is the detail of the process.

Infinite source

When you’re writing a book, you’re in a research mood much more powerful and motivating than usual and your brain will look for ideas for your book constantly with information, scientific studies, case studies, etc. All this will stimulate your creativity to make articles or videos.

Share

share

Share your book’s contents as quickly as possible, allowing you to see how people react to a theme or a chapter. When you know people’s reaction, you can correct your content if you see that it doesn’t interest anyone or change the way you present or write that. There are also people who will give you additional information.

Share allows you to avoid losing 2 years of your life writing a book in your bedroom and on the day of publication, no one wants to buy it because it’s not interesting.

Now it’s up to you to choose the content’s type with which you are most comfortable, written or video version. As you know, each one has its advantages and disadvantages.

But it’s always possible to give an excerpt from your book on a theme and start doing trailer videos while waiting for the book’s publication.

Write your book

It’s really interesting to write a book at any stage of your entrepreneurial life (beginner of expert) and it’s easy to write a digital book (e-book). All word processors convert a text file into PDF and it’s really cool.

Share your book’s content regularly with you audience in a text or video format to update your book’s contents and meet the needs of your audience with a theme that interests you. In addition with this process, this will create you unexpected opportunities that will help your to grow your business.

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)

become your own personal trainer

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

If you didn’t read the Part 1 , click here 

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 ?

Crowdfunding and blog

crowdfunding

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

Use a crowdfunding’s platform is interesting to create a product. What is also cool is that by looking at projects we can have an idea of the future products.

Crowdfunding allow you to sell a product before creating it but there is a difference compared do the Lean Startup method  :

  • With the Lean Startup method, a startup must create as soon as possible a prototype (minimum viable product) to test it in the real world (the market).

  • With the crowdfunding, a product must be of sufficient interest to people to invest their money in the project. It’s mainly a relationship based on trust, people believe your promises.

Crowdfunding

crowdfunding

Crowdfunding’s platforms have their own rules to protect their communities. Imagine you need $300 000.- to create your product. Unfortunately you can reach only $200 000.-. As you have not reached $300 000.- required, the money is refunded to people. Nobody lose money.

The truth is that sell content on crowdfunding’s platform is very difficult. Video games work well, there are video games that reached $1 million. Movies and short films also work well. For exemple, fans of mangas or comics make a movie about their heros. On the other hand, books are really a small percentage.

For an author it can work but you already have a large community, already have an authority or already have credibility in another area.

If you start from scratch and you want to create a blog but nobody know you and you don’t have a community, it will be extremely complicated to have funding with this type of platform.

And the reason is very simple, everybody know that we can create a blog for free.

Self made

self-made

And it’s precisely because it’s free (or not expensive) that makes the blog’s strength.

You can create a blog today from your home and work on it (part-time) next to your school/work.

With a good strategy, you blog is a company. Do you know how it was 30 years ago to start a company ? You needed to have a minimum capital and you had to do a market research by buying files or paying experts. Now with internet, you can do it from your home, it’s cool.

To have a blog that work well, you need to have a strategy and one of the points of the strategy is to reduce your distractions. Decreases distractions that prevent you from evolving your blog. A distraction I’ve decreased is the number of hours watching TV show or Youtube. I spent easily 3 hours a day watching what doesn’t matter, now I decreased to 45 minutes.

With Youtube, I subscribed only 13 channels and it’s channels that learn something or motivate me to develop my blog.

stephane andre youtube subscribe

To have a blog, it’s a little bit utilize the Lean Startup method because your’re quickly in touch with reality to see if what you are doing interest people (number of views), you use feedbacks from your community to improve your content and you build your audience little by little so that your blog become a real company.

Have Ideas To Create Content

idea

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

The most important thing : Write your ideas

When you have an idea, you write this idea right away in your notebook or in your smartphone (I advise you Evernote ).

Look at how it was when I didn’t take notes for my ideas. Boom, I have a great ideas. I tell myself : « Don’t worry Stephane, this idea is amazing, I’ll never forget it ! ». The next day, I wake up and I know I had a great idea but I forgot what it was. Do you know that, right ? This is why writing your ideas is very imporant.

Learn about your passion

passion

What I do to have several ideas a day, it’s first to create content about a passion. Talk about a topic you’re passionate about automatically gives you ideas. Read a lot and watch a lot of videos about a topic you’re passionate about. Having discussions with people who share the same passion as you and participate in training to develop your passion.

Others places to work

different environment

Travel or go to different places in your city (university, park, library, railway station, airport). Being in an other landscape or an other environment (calm/dynamic) is inspiring, it opens the mind.

To ask questions

ask question

Ask questions to others. By exemple you can ask this question to one of your friends : «  Imagine that I can write an article on anything. What would you want ? ». The answer will give you several ideas.

With these tips, you’ll have more ideas in your notebook that time to write article or create content. This is so cool.
