Is it light or heavy for thin people to start fitness? How long can it last if the weight is small? Also, I exercise in the gym and the equipment inside.
Do you want to gain muscle, shape or lose weight? Thin people should first supplement high-protein food, eat less and eat more meals, and do more to destroy the feeling of muscle reorganization ... If you want to gain muscle, you must practice weight in the gym, which is very important, and the shaping is different. Just use what you like by hand (ω).
