That sounds great. I can take creatine and increase muscle mass without working out! Hmmm. That sounds a bit too good to be true. Is it really that simple? How would you respond? a. Your muscle mass would likely increase, but that's probably due to an increase in muscle water. However, creatine supplements may allow you to train harder, which in turn can increase muscle mass. Working out is still an important part of the picture. b. Your muscle mass would likely increase because the creatine makes the muscle produce more protein. Training can be reduced since the creatine supplement acts like a substitute for working out. c. It really is that simple. Creatine supplements increase muscle mass, which increases muscle strength, which eliminates the need for working out.
