Go online to buy a set of American GoFit super muscle fitness tension rope elastic rope suit. Comprehensive strength training equipment is comparable to Trx. Similar equipment is also acceptable. I use 15 kg now. I think that's enough, 50 yuan. It can help you complete the chest grasping action of the bird in the gym, mainly to help you increase the pumping and congestion of your muscles. This action is very good. Then I'll tell you a few moves that can help you practice the whole chest muscle group. An action can be replaced by a water bottle. Ordinary push-ups-deltoid toe; Diamond push-ups (narrow distance)-inner chest; Wide-distance push-ups-there are more belts in deltoid muscle, which can be brought to pectoralis major; Push-ups with high legs-just lift your legs and practice your chest; Side push-ups-that is, stretching with one hand as the fulcrum and the other hand holding a water bottle, can exercise more pectoralis major muscles. The number of groups is generally 15-20*4, until exhaustion and the operation is over. Make several groups of birds with elastic rope to make the pump feel stronger and achieve failure. I hope I can help you.
