Hey im 17yrs old 5'9" 230lbs. I started lifting in May and i was 280lbs. The last 3 weeks i stayed the same weight. I added in 2 miles of running 5 times a week 2 weeks ago and i still vary from 228-230. I use to lift heavy weights light reps. Now my goal is to be 180lbs cut, ripped, and defined. Im going to keep on running but should i now switch from lifting heavy weights and turn to lifting lighter ones to get my body out of its plateau and burn more fat?
