A high school American football player would like to increase his strength and muscle mass. His average caloric intake of 2200 k
cals/day has allowed him to maintain a bodyweight of 160 lb (73 kg). He would like to gain 10 lb (4.5 kg) by eating an extra 500 kcals/day and following a resistance training program. Assuming all of the weight gain is lean body mass, approximately how many weeks would it take for him to reach his desired weight?
