How can I defend myself? I am 18, male, weighing only 80 kg, with a height of 164 and extremely underdeveloped muscles. 1 How many? I see.
Indoor horizontal bar+10KG dumbbell+abdominal muscles (three-wheeled version)+skipping rope. Round after round of practice, everything will continue after reaching the limit, lasting for 2 hours and 3 months every day, gaining weight and muscles, and exerting the strength of 100KG, and screwing whoever you want, provided that the nutrition can keep up.
