Muscle hypertrophy involves an increase in size of
skeletal muscle through an increase in the size of its component
cells. Hypertrophy can be broken down into two types of categories:
myofibril and
sarcoplasmic. Each of these specific types of muscle hypertrophy will result in increasing size of cells, but not of equal effect.
Sarcoplasmic hypertrophy is focused on increasing the actual size of the muscle, and less on increasing strength.
Myofibril
hypertrophy will focus more on strength increase and less on an
increase in the size of the skeletal muscle. Muscle hypertrophy is not
achieved within minutes or days, rather it takes months of consistent
training and proper nutrition to see its visual effects on body
composition.
How to Build Muscle Strength
If your main goal is muscle strength then you should create a
weightlifting program with exercises that adhere to the following

Amount of Weight Lifted | 85% of 1RM or more |
Number of Sets Performed | 2 to 6 |
Repetitions Performed Per Set | 6 or less |
Rest Period Between Sets | 2 to 5 minutes |
How to Build Muscle Size (Hypertrophy)
If your main goal is muscle size, or hypertrophy, then you should
create a weightlifting program with exercises that adhere to the
following guidelines:
Amount of Weight Lifted | Between 67% to 85% of 1RM |
Number of Sets Performed | 3 to 6 |
Repetitions Performed Per Set | 6 to 12 |
Rest Period Between Sets | 0.5 to 1.5 minutes |
How to Build Muscle Endurance
If your main goal is muscle endurance then you should create a
weightlifting program with exercises that adhere to the following
guidelines:
Amount of Weight Lifted | 67% of 1RM or less |
Number of Sets Performed | 3 to 6 |
Repetitions Performed Per Set | 12 or more |
