How Fast Do Our Muscles Grow

Guessing for the answer of this question is actually what almost all of us would do. Including me until I read about the study, done by U.K. scientists, in which study they discovered that it takes as little as 3 weeks to see noticeable growth of a muscle.

What happened was the researchers closely monitored people who did leg extensions for four sets of seven reps 3 times a week. They found that the athletes gained on average 0.2 percent muscle mass a day.

If you ask me that’s huge. Think about it for a moment. If you train certain muscle group 3 times a week that’s 156 workouts a year. If this muscle group grew with 0.2 percent a day that makes for more than 70% increase. Now, tell me if you wouldn’t like that?

Of course there is no such thing as constant and steady muscle growth, but still if you ask me I’d be content with even half of that increase in a single year.

In conclusion this study is another strong vote for the “train each muscle group 3 times a week - intense” concept, which is becoming more and more a staple in the sport of bodybuilding.
