The first is called Myofibrillar Hypertrophy.

This type of muscle is much stronger and denser.

 You achieve this kind of muscle with heavy 

weights and lower reps.

 

The other type of muscle growth is called 

Sacroplasmic Hypertrophy.  It's a bloated muscle

that's soft and not actually use full besides looking

good.

 

Below you'll see a picture to show you what I mean.

 

 

 

If you already have the size you want and you'd rather

focus on building dense strong muscle you should put your

efforts toward Myofibrillar hypertophy. 

 

A great program to follow for this type of training is,
The Grow Stronger Method.

You'll learn about building muscle. Not the puffy water

filled kind of muscle, but rather the strong performance

based kind.

 

Keep training hard,
