Hello, i was wondering how i could lose weight efficiently. i am a pretty big guy, 200 pounds, 5'8. i run alot, but i cannot seem to sweat. only in the lower back area i can sweat, not the upperback. my head doesnt even sweat. im wondering if i go on the bike for 20 minutes then do strength training (upper body then next daymid then next day lower) would work. ive been working out for about 2 months, seen results, but lost it during the summer. please help me out.
