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

Hypertrophy

When I started to train, I thought I can increase the amount of muscle fibers with strength training program. The truth is we have a specific number of muscle fibers. We can only increase the size of our muscles fibers, this is hypertrophy.

I discovered that there were several hypertrophies. Usually when people talk about hypertrophy, it’s sarcoplasmic hypertophy.

  • Sarcoplasmic hypertrophy

    This hypertrophy allows you to increase the amount of sarcoplasmic fluid in your muscles. This can increase the size of one of your muscles by 30 %.

  • Myofibril hypertrophy

    This hypertrophy allows you to strengthen your myofibril, the part of the muscle that contracts. This increase the strength of your muscle fibers, build strong muscles and super dense.

  • Transient hypertrophy

    This hypertrophy allows you to increase temporary the size of one of your muscles during and immediately after an exercice due to an accumulation of fluid (I still don’t know if it’s the sarcoplasmic fluid or glycogen) in the intercellular space. This is what gives the effect « the pump ».

To summarize to buid a muscle super dense and strong, it’s myofibril hypertrophy. To have bigger muscle, it’s sarcoplasimic hypertrophy. Transient hypertrophy is temporary and appears in the other 2 hypertrophies during the training.

During a strength training, here is what happens :

  • During an exercice you’ll break muscle tissue. Your body will repair this muscle and it will become stronger. Whenever you break muscle tissue, your body will do this process.
  • When you increase the number of repetitions, you increase the storage of glycogen in your muscle. This is where you muscle gets bigger.

For the training program

Strength training isn’t just lift weights. It’s more interesting and more complex than that.

Here are details :

A little help for this Excel’s table

  • Repetition (Rep) => An exercice is composed of a starting position and an arrival position. A repetition is when you make the movement from the starting position to the arrival position and you return to the starting position. All that make a repetition. For exemple when you squat, the starting position is standing. The arrival position is when your thighs are parallel to the floor and you return to the starting position, standing.

  • X Rep Max => This is the number of repetitions with the heaviest weight you are able to control. By exemple, 1 Rep Max (1RM), is that the weight is so heavy that you can do only one repetition. 10RM, is that you can control the weight successfully to do 10 repetitions. In the 11st, it’s the failure.

With this Excel table, you can have an idea to how you can do to gain stength (myofribril hypertophy) : A low number of repetition and heavy weight. To increase the size of your muscles (sarcoplasmic hypertrophy) : A high number of repetition and light weight.

ATTENTION : This Excel table give us an idea of how to do to reach our goal. It’s not something specific. When you do a high number of repetition to increase the size of your muscle, you gain also a little strength. Our body is smarter than us.

It’s for this reason I never understand girls or women who don’t want to « get bulk », so they do 3 sets of 16 repetitions or 5 sets of 1000 repetitions with a dumbbell of 2kg (4.4lbs).

It’s hard for a girl to bulk, no matter the weight or the number of repetitions, if they want to increase the size of muscles, that’s exactly what they have to do because it would make sarcoplasmic hypertrophy.

Recovery

recovery sleep

I’m sure you’ve already heard that muscles are built in the kitchen, not in the gym.

It’s because when you’re in the gym, you break your muscle fibers. When you’re outside of the gym, your body heals and your muscles become bigger and stronger. So it’s important to take a recovery’s day in your strength training program.

The general rule is to wait 40 hours before to work the same muscle group again.

Remember that your muscles works in team, which means that when you work your chest, you also work shoulders muscles and arms muscles.

Everyone at his own pace to recover, it depends on diet, sleep’s quality, age workout and other items like stretching or massage.

The basis of strength training is 4 days of training per week and one recovery’s day.

Sore muscles or DOMS

DOMS is the acronym for Delayed Onset Muscle Soreness. Sore means that your muscles haven’t recovered to 100 % (hence the « delayed onset »). This can last 1-2 days after your workout and this is normal. The process for your body to rebuild your muscles takes several days after a workout.

It’s normal that you have sore muscle for several days after your first training or after a long break. With each exercice, your muscle gets used to a movement and adapts to the stress caused by this movement so that you have less sore muscles. Stretching helps you to decrease sore muscles.

I think you motivated now, to start a strength training. Don’t worry, there is a lot of stength training program great for beginners on internet. The book « Starting Strength » is excellent for beginners, the Excel’s table of this article comes from this book.
