The way to increase muscle strength when working out is to let the muscle withstand the maximum load to do plyometric training. Progressive resistance plyometric training is recommended to increase muscle strength quickly. First of all, we should measure the maximum load that the muscle group can withstand for 10 consecutive isotonic contractions, that is, to measure the maximum muscle strength as a reference, to develop a daily exercise, daily training is divided into 3 groups. The first group took 50% of the maximum exercise load for 10 repetitions, the second group curved 75% of the maximum load for 10 repetitions, the third group took 100% of the maximum load for 10 repetitions, resting for 1 minute between each group, and then repeat the maximum load on the muscle after 1 week. If the muscle strength has improved, then according to the latest muscle maximum load customized training intensity and plan for the next 1 week, after training should also be supplemented with a large amount of protein, it is best to consume protein powder or beef to help muscle growth.
