I am currently 15 years old. I am 6' tall and I weigh 157 pounds. I am not fat however I am not comfortable with my shirt off because of my unappealing, "skinny-fat" stomach and chest. My goal is to be proud of my body and comfortable with a shirt off by next summer. More specifically, Defined Upper body and core. My workout plan is geared towards slow, but steady progress. I am aiming towards small lifestyle changes and consistent exercise to reach my goal. So far I have made a simple plan open too tweaks as I go on. Here's my plan: I Bought a simple set of dumbells, and I am alternating between Upper body, and Lower Body workout days. For the workouts I do 4 sets of 10 Bicep curls, Tricep Extensions, Hammer curls, Tricep Kick backs, spyder curls, and finally push ups. On lower body days I do Weighted Squats, Weighted Crunches, Lunges, Halos, Goblet Squats, again 4 sets of 10 each side. Currently using two 15 pound dumbells but will increase weight as soon as I feel comfortable with the increase. I finish each workout with a protein bar. On top of the daily workout, I fill my day with plenty of cardio, and trying to make better dietary choices. Can anyone tell me if I will reach my goal with this program? if not, what changes can be made?
