Perhaps this is the wrong way to approach this problem, but i need some help. I have a 20? year old gym set in the basement (think separate exercises, stuck on 1 frame) that has a benchpress that doubles as a squat rack, barbells, a set of weight and pulley systems (one you pull up on, the other you pull down on), and a weighted leglift thing. So thats all i have to work with. Im 5'11, 195, with maybe a centimeter of fat on my arms, and like an inch on my chest and stomach. The doctor says im fine (not medically overweight, relatively fit), but im looking to get more fit, both by increasing muscle strength and losing fat. The catch is, i dont know how to diet to lose the fat, without losing muscle too. Im looking for advice on food and exercise, with my goal being ~170 lbs (assuming i dont gain much weight in muscle, im fine with non fat-weight gain). Thanks P.S. Im 15 1/2, so i dont have free reign with my grocerys, nor do i have transportation to a gym, let alone the $$ to buy a membership.
