My height 166, weight 55. I want to keep fit, exercise my muscles and my abdominal muscles now. I have a lot of fat in my stomach and thin arms. Should I lose fat first?
Lose fat first, then exercise. Pay attention to diet and sleep during fitness. Eat more high-protein and high-carbon foods in your daily diet, eat more vegetables, fruits, eggs and beef, and go to bed early and get up early every night! Wait until the later exercise intensity is high, then consider adding some protein powder! You can go to the physical store pqfitness to see which one suits you.
