how much protein do i need while working out
An adult athlete looking to build muscle should consume roughly 0.64 to 0.82 grams per pound of body weight, according to Montana State University-Bozeman's Sports Nutrition site. This equals about 89 to 114 grams of protein per day for a 140-pound person. In comparison, the recommended protein intake for a normal, physically active adult is 0.4 grams of protein per pound.
