Whats the best way to stretch before working out the upper body(chest, bis, tris, back)? How long should you stretch for to ensure that you dont injure your muscles by working them cold?
I need to know what the best supplement is for gaining weight. Im 18 and I need to gain bout 25 pounds to be in my ideal weight range for my height. :confused: Also, what is a good diet for building lean muscle mass. I have a good metabolism, so I burn fat pretty easily.
