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


Standing between the pulleys, arms outstretched and take the handles with a  supinated grip :

  • Inhale and flex your arms

  • Exhale at the end of the movement

This exercise is good as a movement for the muscle’s definition during a biceps session. This exercise train biceps, mostly long head because it stretched and tensed with your arms in cross. The brachialis, monoarticular flexors of elbow work too.

Don’t do this exercise heavy, the key is to be focus to feel the contraction from the internal part of the biceps. Sets with high reps give better results.

arm biceps anatomy

When the hand is in pronated grip, the distal tendon of the biceps is in part wrapped around of the radius.

arm biceps anatomy

When the biceps is contracted, the force exerted on its distal tendon rotates the radius on its axis and keep the hand in supinated grip.

Note : Apart from its role of flexor arm, the brachialis is also the most powerful supinator muscle

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


Standing or sitting with a dumbbell in each hand with a semi-pronated grip like a hammer :

  • Inhale and flex your arms simultaneously or alternatively
  • Exhale at the end of the movement

This is the best exercise to develop the brachioradialis. Biceps and brachialis work too. The short and long radial extensor carpi work a little bit.

Less effort law

less effort

To save some energy, the muscle will use initially the most straight fibers and located in depths in the muscle. More effort increases, more the muscle will use superficial fibers to do the movement.

Everybody think when we train hard, we train the muscle in depth. In reality, more we train hard, more the muscle will use fibers in the outer part of the muscle.

Deep and straight fibers are generally slower for contraction but more resistant to repetitive effort than exterior fibers.

3 months later, they get married. 9 months, they had a baby, Wayne. Now Bobby must work harder to support his family but the problem is he can’t train because he has no more energy. When he looks his mirror, he sees something on his abs growing and growing.

He notices than Stacey gains also weight. Bobby and Stacey are depressed because of theirs bodies. They remember the selfies and they’re more depressed. Bobby suffers and everytimes he says to himself : « This monday, I go to train ! » and when the monday comes, he has no more energy.

Study Case An Overweight Father

overweight father

I watched a Jamcore DZ’s video  and there is good stuff.

This is a study case from a Jamcore DZ’s fan. It’s a guy who know he has a weight problem. He’s afraid but he doesn’t know what to do. Be careful, if you are not careful it could happen to you in the future then stay focus everydays.

Study case

study case

This guy watch often Jamcore DZ’s video with sweet drink and cookies and dreaming to have an athletic body. He’s 40 years old, 110kg (242.5lbs), 109cm (6’2’’) and he likes cookies, nutella, sweet dring et he drink very little water. He likes when his wife cooking and he eat everything she cooks. Now, he is motivate and he bought a traning program for endomorph (it’s a guy who store fat quickly). His story, he’s a public servant. When he began his job 14 years ago, he weighted 70kg (154.3lbs). Sitting and snacking, he weight 110kg (242.5lbs). There is a gym in his workplace but he never went.



This guy is in a situation that can cause heart problems, blood pressure problems and heart attack. People with a lot of fat in the stomack have often heart attacks. This isn’t to scare but this is the truth. The fact that he reconizes the problem and he bought a training program is excellent.

One obstacle is that his wife don’t cook meals good for the body. Why she cooks these meals ? Because she just want to please him, it’s normal. It’s hard for him to change because he lacks of discipline. He’s a victime of his own routine et sugar killing him. Yes, sugar.

Help is there

hepl is here

Firstly, an agreement in the couple must be done, he must discuss with his wife to speak about this situation. Children can be include in this agreement by this way all family work to have a better health and a better life style. This is the most important thing, all family want reach the same goal.

Secondly, change food. Throw out junk foods of closets et replace them with healthy foods. Really, throw out junk foods. No more white sugar, cakes, sweet drinks, white bread, fruit juices, sweet yogurt, sweet cereals. Buy fruits, oatmeal. Learn to cook healthy meal. Study ingredients, it’s easy now with internet. Why we’re tired after school or work ? It’s because we ate junk food all day. We ate sugar et we don’t do physical exercices.

If all family do it, results will come fast and together. Be organized. People who take care of their health do it with all their family, cook together, share healthy meals et training exercices. Be with friends who have same interests to be in a good health. Don’t be with people who don’t care about their health because they’re screwed and they want to make you sink with them. Be with people who like to train too.

Take one day per week to eat something you like, everything you want. One day, breakfast or lunch or diner. This is will not destroy your progress and it’s good for your morale.

Follow a training program and do it seriously. People prays but don’t act. We need to act everydays to change ours lifestyle. A important thing is to organize in advance because if you’re not organize in advance, you’re screwed. If your foods is organize in lunch boxes, in the morning, when you wake up, every meal of the day are ready. From the morning to the night. Rice, tuna, vegetable and a fruit. Event if your friends said to you it’s weird, don’t heard them.

At the beginning, people will criticize you but when they will see your body and your behaviour change, they will ask you a lot of questions, you will attract people. Your energy is different because your food is different. Your belly disappears, you buy new clothes (don’t spend all your money in clothes, be careful). You feel good, your wife and children love you more, it’s happiness.

Body is mind.

The Bulking’s Myth


I read an article on T-Nation  and here is what I learned

Here’s what you need to know :

  • After a certain point, your ability to gain muscle will not go faster by consuming more food.

  • The body can’t build more than a few kilograms (pounds) of muscle in a month. Remember that the weight you gain is not only muscle.

  • There is a better way to gain muscle. Don’t used the bulking period as an excuse to eat junk food.

The gluttony game

To have more volume you have to eat more, we agree. You will be able to gain a large amount of muscle mass only if you eat enough calories and nutrients to help your body to build muscle. For those who take steroids, that’s another story. In fact, if you don’t eat enough, it’s possible that you lose muscle even if you train hard. More you eat, more you grown.

But not so fast

If you don’t eat enough, your muscle growth will stagnate but that doesn’t mean that if you eat more, you will gain much more muscle.

A major mistake that you can do when you train to have a muscular physique and aesthetic, it’s eating too much junk food and have a high percentage of body fat to boost your muscle growth.

When you are natural, your body has a limited ability to build muscle. The amount of muscle you can build depends on the ability that your body has to synthesize new muscle tissue from protein you eat.

The ability of your body to synthesize the protein depends on your natural testosterone levels, your testosterone with your cortisol ratio, your insulin sensitivity and your genetics.

You can eat the amount of food that you want, you can’t change your ability to synthesize protein. Overeating will increase your body fat percentage.

Your body is a construction worker

body under construction

Imagine that your muscles is like a house you trying to build. The bricks are amino acids (from proteins) and the money to pay construction workers are carbohydrates and fat you eat.

If you don’t give enough bricks (protein), they will not be able to build the house as fast as they can. A deficiency in protein means a slow muscle growth.

If you don’t pay your construction workers enough with nutrition, they will not be motivated to work hard. If you really don’t pay your construction workers, they will even destroy your muscles (catabolism due to a too low calories intake ).

In summary, if you don’t eat enough protein and calories, you will gain muscle very slowly.

Giving more bricks (protein) to your construction workers , they will be able to build the house faster. But at some point, sending too many bricks will not speed up the construction speed. For example, your construction workers can add 1000 bricks per day in a wall. If you give them 2000 bricks, it will be useless because it will exceed their ability to work. This is the same thing for the salary (calories).

The athletic threshold

« But I gained 6.7kg (15lbs) in 3 months and I didn’t gain fat »

This is something we often hear. If it’s possible to gain only a few kilograms (pounds) of muscle per month, why so many people say they have gained much muscle without gaining fat ?

It’s possible to gain muscle without gaining much fat and the answer is : an athletic body. An athletic body isn’t the body you see in bodybuilding competitions. An athletic body has a body fat percentage between 10-20%.

The guy believe he gained 6.7kg (15lbs) of solid muscle because visually, he looks to have kept the same body fat’s percentage. But if we look in detail, he gained 2.7kg (6lbs) of muscle, 3.1kg (7lbs) of glycogen and 0.9kg (2lbs) of fat in a period of 3 months.

Here are two situations :

Situation A

  • Go on a bulking phase

  • Gain 11.3kg (25lbs) over a period of 6 months

  • The details of 11.3kg (25lbs) is 2.2-4.5kg (5-10lbs) of muscles and the rest is 0.9-1.8kg of glycogen (2-4lbs) and 4.5-6.8kg (10-15lbs) of fat.

  • To lose the excess fat, you have to do a strict diet. If you are extremely strict, you can expect to lose 0.4-0.9kg (1-2lbs) of fat per week without losing muscle.

  • The best scenario is 6-12 weeks to lose fat. Otherwise 12-20 weeks.

Situation B

  • Increase your calories but just enough to give your body the nutrition needed to maximize your muscle growth.

  • You gain 0.6kg (1.5lbs) of muscle per month with less fat.

  • After 6 months, you gain weight 2.2-4.5kg (5-10lbs) but only 1.3-2.2kg (3-5lbs) of fat.

  • To lose fat, you need to do a diet for a month.

The best way

Many people ruin the potential of their body with the internet gurus tips that advise eating as much as possible (even junk food). Result, a lo of unnecessary fat that gives the impression of being muscular.

Many people don’t eat enough to help muscle growth but eating too much or eating junk food isn’t the solution. We must calculate the number of calories that we have to take a day and select food throughout the year.

Did you go in a bulking period ?
