well... most of it is false yea.... go to any good gym they'd tell you all this is false....

and hmm the first one is true actually... research shows that if you do 15 repetitions with 10 pounds and 5 repetitions with 25 pounds , your muscles are still doing the same amount of work, and you could actually build the same kinda body a big bulky body builder would build( in terms of muscle definition and not strength)... ..this is wat i read in TOI... i think..
