Strength training, also known as resistance training, can get you into a better state no matter what form. It should be noted that the recovery of muscle strength training takes time, and it is best to do it every other day. Moreover, warm-up exercises should be done before strength training to stretch muscles and prevent strain; You should also do some stretching exercises after training, so what should you pay attention to when exercising upper limb strength? Before training, the range of joint motion and muscle strength of the training site should be evaluated, and the training method should be selected according to the evaluation results. There must be sufficient warm-up activities before training to warm up the muscles, ligaments, joints and cardiovascular system that are about to exercise. Muscle soreness is a normal phenomenon in a short time after muscle strength training, which is beneficial to the protein synthesis of muscle fibers. However, severe muscle pain during exercise suggests excessive exercise intensity, while increased pain or fatigue the next morning suggests excessive exercise; People with hypertension, coronary heart disease or other cardiovascular diseases should pay attention to the cardiovascular reaction during exercise to avoid cardiovascular accidents due to overtraining.
