Here is my question: Is it possible to gain strength without gaining body weight? For instance, if you have a well-trained athlete at, say, 205 lbs. with 9% bf, who can squat 500 lbs. for one rep and bench press 335 for one rep, is it possible for this same athlete to increase these max lifts to a 600 lb. squat and a 400 lb. bench press without gaining any bodyweight at all? How strong can one become before gaining bodyweight becomes necessary? Is it totally genetic as to how much strength the body produces at certain bodyweights?
Also, this really gets me. How can you have someone that is, say, 6’2", 250 lbs., 10% bf, with a very impressive physique, have weaker max lifts in all power exercises (cleans, squats, deadlits, bench) than someone who is, say, 5’10" and 205 lbs. and 9% bf?
