Can you only get muscles by lifting weights?
Or are there other workouts you can do to get muscles?
Because I%26#039;ve been using these Billy Blake%26#039;s workout videos, and hes intense and he does alot of arm and shoulder workouts.
Muscle gain from lifting weights are effective but aren%26#039;t the only way to gain muscle other ways are sports,martial arts,eating healthy and much more....
