I was thinking about drinking some Monster Mass to gain 15-20 lbs for football tryouts in late July. What else could I do to gain that weight in 4-5 months?
Figure out how many calories you burn playing football, the gym and even daily life and then basically eat more than what you burn and you'll put on the weight; but you must make sure to eat healthy because you don't wanna start eating tons of junk food, do you more bad than good, trust me!!
