i am 16 years. i am 5'9" and only weigh 130 pounds. i have been working out at least three days a week for the past year and a half and can only bench 120 pounds. i think it might be because i do have long arms, thus it is harder for me to push the weight up after it touches my chest, but i try to deny it. i need some input on what a long armed skinny kid can do to bulk up with muscle mass and strength. i have track and crosscountry practice all year round except for the winter, so i dont have much time to workout 5 days a week as i do in the winter. i am in dire need of some weight lifting routines that will help me out and help me gain weight as well as strength.
