hey im 15 and male, im not fat but im a tiny bit chubby ... but my enviornment from my brothers is all muscle and thin, they both workout regularly and sorta shove it in my face... i do have some muscle because i have been lifting dumbells... my equipment is propably about 20 lbs on each dumbell that i use.... im about 160 and 5'5 - 5'6..mostly my fat is my upper legs and torso... i was wondering the best ways to get 1) muscular calves 2) thinner upper legs 3)smaller upper chest area 4) and thinner upper arms ... im joining the wrestling team in 3 months (september) and want to be in shape in that amount of time at the most but preferably earlier than that, i also want to begin either running/jogging/walking but am not really a good runner, im looking for advice...if theres any way to help, i appreciate the feedback
