I exercise and am bulking up, but after a year i am in the same size pants, waist not getting smaller. can you advise?

Maintain consistency: Clarify your goals and taper your workout. Accordingly. "bulking up" implies lifting heavy weights for low repetitions. If your goal is to narrow your waist and lose fat, focus on cardiovascular training and full body movements. Also, the cardinal rule when changing your physique is to eat healthy and consume less calories than you expend.
