i used to do 2 gallons, now i cut it down to about a gallon and a half, its really not hard to drink a gallon at all, and yes it takes more than just starting now to get a "beach bod" ive been lifting since i was around 15-16 and im 22 now, and im close to where id like to be, but not just yet, diet has more than u think to get in shape and look better, its not just all about throwing around weights....cardio to burn off the fat from the muscle, spot reduction exercises will NOT do that as much as u think it might...and please for gods sake do not put a ton of weight on the bar in ANY exercies, ur going to end up either 1. hurt urself. 2. look like an idiot, 3. do half reps or 4. all of the above, ur cheating urself trying to do so much weight and not doing an exercise in ur full ROM, lighten the weight and perform the rep properly, and u will see results quicker
