I weigh 117lbs and I am 5' 7". I was in a weight training class last year. I have nothing to show for all my hard work. The amount I can lift has increased, but nothing shows. I have a really high metabolism. I can eat ANYTHING I don't gain weight. This summer I was hoping to go to a local gym and work out. What should I do differently? When I was in weight training I did box squats, dead lifts, power lifts, curls, pull ups, chin ups, leg presses, bench press, inclined press, etc. What can I do differently?
