Floor Hip Abductions

foor hip abductions

I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.

Lie on your side with your head and shoulders on line :

  • Raise your leg to an angle of 70 degrees (at the most off the floor, always keeping you knee extended).

 

  • Back to the starting position

This exercise works gluteus medius and gluteus maximus, It’s possible to make this movement with a large amplitude or a small amplitude. You can do an isometric contraction holding the position for a few seconds at the end of abduction.

You can raise your leg slightly forward or slightly backward or vertically.

To increase the difficulty, you can use a resistance band or strap a soft weight around you ankles or use a low pulley.

Add a Reference Line

reference line tableau data science

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

In the previous article we learned how to work with aliases. We will learn how to add a reference line in our bar chart.

Before I start, I’ll show you a trick in Tableau.

In our bar chart we can see the labels in this order : percentage and below : « Stayed » or « Exited ».

We will reverse this order. You go in this rectangle.

And you place the label « Exited » above the label « SUM(Number of Records ».

Look, the label « Stayed » is above percentage.

reference line tableau data science

With that, we can understand the bar chart more easily.

Let’s add a reference line, let’s go . But before, I think you’d like to know why I’m talking to you about a reference line.

A reference line helps us to compare bar chart results with a benchmark. This benchmark is represented by this reference line.

In our case, the benchmark is the percentage of clients who left the bank in our sample of 10 000 people.

The first thing to do is find this percentage in our bar chart. To be able to do that, remove « Gender » from « Columns ».

reference line tableau data science

Boom, we have a new bar chart.

reference line tableau data science

Look, we only have the percentage of clients who left the bank and the percentage of clients who stayed in the bank.

We see that on our sample of 10 000 people, there are 20% of the clients who left the bank and 80% of the clients stayed in the bank. This means that the churn rate (client departure rate) is 20%.

What we’re going to do is we will add this churn rate in our A/B test. To return to our A/B test, press 2 times on Ctrl+Z or Command+Z or you can click 2 times on the « Back » button in the menu bar.

reference line tableau data science

Now we know that the average clients who left the bank is 20%.

We will add a horizontal line in the Y axis (Y = 20%) to compare the 20% of the churn rate and the 2 categories male and female.

Let’s go. Right-click on the vertical axis (Y axis) and select « Add Reference Line ».

reference line tableau data science

A window appears with several options.

You have the choice to add a line, a band, a distribution or a box plot.

We will use the line for the entire table.

Click on the « Line » button and activate the « Entire Table » checkbox. In « Value » selects « Constant ».

reference line tableau data science

The constant is 20%, so it’s necessary that you put 0.20 in « Value ».

reference line tableau data science

It’s possible to put a label on this reference line. For example, if the line reference corresponds to a formula, the label displays the formula. But for our case, our constant is 20% and it’s already displayed on the vertical axis so we will select « None ».

reference line tableau data science

For the format of the line, select the continuous line and click on the « OK » button.

reference line tableau data science

We have our reference line is added to our chart.

reference line tableau data science

Here is what we can see. Female clients are more likely to leave the bank than average clients. Male clients are less likely to leave the bank than average clients. 

In our case, it’s obvious to see that because there is only 2 categories, men and women.

Now you know how to add a reference line in a bar chart.

From Beginner To Become Your Own Personal Trainer (Part 1)

become your own pesonal trainer

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

Before to read this article, I advise you to read Find The Gym For Your Goals Part 1 et Part 2; Back To The Source Of Equipment Part 1 et Part 2; Back To The Source Of Human Strength Part 1 et Part 2.If you already read it, continue and have fun.

A strong body is a healthy body, you have heard this many times but it’s not easy to do. Starting a new workout can be intimidating. It’s, for this reason, a lot of people fail.

How you will train

gym training

To start, you have to find out what kind of strength training you want to do. It depends on the equipment and your goals. Here are several types of training programs :

Bodyweight

With a bodyweight training, you need little equipment (or not at all) and you can train everywhere (home, hotel, playground, workplace). As long as you have room to move, you can train.

If you like bodyweight training, take a pull-up bar and a set of gymnastics rings. If you’re really a beginner, an exercise band  can assist you in the movement like pull ups and dips.

If is that you can do bodyweight training without equipment, the disadvantage is that you need to constantly change exercises difficult to be sure to progress.

Dumbbells

Dumbbells are excellent for starting a workout with weight for several reasons.

First, gyms always have a good set of dumbbells. If you want to train at home, you can buy a set of adjustable dumbbells (that’s how I started in my bedroom).

The second reason is that dumbbells allow you to add a small amount of weight to do an exercise and exercise with dumbells are less intimidating that exercise with a barbell. For example, if you’re a beginner, starting with a 20kg (45lbs) barbell is a bit too much.

Dumbbells also allow you to work your symmetry and allow you to balance the strength of your right side and left side of your body. It’s ridiculous to have an arm or a leg extremely bigger and stronger as the other.

If you can’t finish a repetition, it’s easy to throw dumbbells on the floor compared to a barbell. For a beginner, it’s excellent for learning movements.

The disadvantage is that to evolve, you need to buy new dumbbells and this can be expensive. A gym membership is handy to avoid this problem.

Barbells

If your goal is to gain only strength, this is the recommended option. Barbell allows you to progress cleanly and quickly by adding a small amount of weight each week.

A barbell is really stable because you use your 2 hands instead of 1 hand for dumbbells so it’s easy to lift heavy (especially for the lower body like squat of deadlift). For exercises like the squat or the press, you can use the rack to load and unload weights safety.

The disadvantage is that to do this at home, you need to have a squat rack, a barbell, a bench and enough weight plates in your house or in your garage. A gym membership is handy to avoid this problem.

What’s the best way to train?

The barbell is optimal for gaining strength. Bodyweight training is good but you have to seriously motivate you to train at home.

Sometimes you have to adapt to the situation to be able to do your training. When I travel a bodyweight training is perfect if I don’t have access to a gym.

But the best workout is when you lift heavy. Nothing can replace squat, deadlift and body weight pull up.

There are also other ways to have a strength training like rock climbing, yoga or parkour.

Choose the program to follow

gym training program

Never go to the gym without having a plan. To get results, it’s necessary to have a plan to track your progress.

For to make a lot of progress, a beginner can have a full body program of 3 times a week with a day off between training days. Be sure that the program you choose matches your goals, A powerlifters will have a different training from a bodybuilder or an endurance athlete.

In my article Back To The Source Of Human Strength Part 1 and Part 2, I talk about numbers of repetitions and their goals :

  • Reps in the 1-5 range build super dense muscle and strength

  • Reps in the 6-12 range build a somewhat equal amount of muscular strength and muscular endurance.

  • Reps in the 12+ range build muscular endurance and size

Many beginner strength training programs say to do 5 sets of 5 repetitions to optimize progress to gain strength.

With a circuit or superset, you do a set of each exercise in an order and you repeat the process.

For example :

  • 20 bodyweight squat

  • 10 push ups

  • 20 walking lunges

  • 10 dumbell rows

  • 15 second plank

  • 30 jumping jacks

  • Repeat all these 5 times to do 5 sets

In traditional strength program, you do a complete set of an exercise, you rest and you do another set of the same exercise and so on.

For example :

  • 10 squat

  • Rest

  • 10 squat

  • Rest

  • 10 squat

  • Rest

  • 10 squat

  • Rest

  • 10 squat

  • Next exercise

If your goal is to be healthy and lose weight, you don’t need to focus on strength, a circuit (superset) is perfect.

This allows you to spend less time at the gym and to make up your high heart rate longer.

If your goal is to have more strength and have more muscle, choose a traditional strength training.

One important thing, your diet corresponds to 80-90 % of your success or failure. The quality of your diet will help you gain strength and lose fat.

When you choose a workout to develop your strength, be sure to increase the difficulty over time. To become stronger, you need to write a plan. This can be to do one more squat, lift 2kg (5lbs) more or do your circuit (superset) 10 seconds faster.

The main goal is to always be better than the last time, this is what ensures the continuity of being stronger and faster.

You can write your own training program or fortunately, there is a lot of excellent beginner program.
