The main source of grip strength is that we can grasp a few times with empty hands to achieve the purpose of training. Because this part of the muscle group is small, it can reach a certain strength without load. Generally, the number of times is used to make a boundary. For example, if you feel sore after 50 times of empty-handed, then take a break and do it for 50 times and repeat three groups. (the number of times should be increased or decreased according to everyone's different situation. In principle, it is mainly because of soreness, so try not to do it again. ).
Straighten your hands, relax immediately after making a fist, straighten your fingers, make a fist again, relax again, and repeat.
Biceps training needs the assistance of instruments. If you don't have dumbbells around you, you can find anything you can grab, or just carry a bucket and repeat the lifting action. The number of times varies from person to person, so that you feel sore. The same is true every time 12 times (the weight needs to be adjusted by yourself), repeat three groups and rest 1 minute. (Try to keep the three groups the same number of times).
Ordinary push-ups can train our triceps, but this action will also train your chest muscles, so you only need to make a small change to focus on your triceps. After the standard push-up posture, reduce the distance between your hands to shoulder width, or even slightly shorter than the shoulder distance, so that the strength will be concentrated on the triceps (chest muscles are still practiced, but mainly triceps), and the frequency is about 15.
Another trick to exercise hand muscles is to choose two bottles of mineral water bottles filled with water, one in each hand, then stand up straight, with your hands drooping naturally, and then raise your hands horizontally. It should be noted that at this time, don't bend over, hold your chest out, control the number of horizontal lifts to about 20 times, and repeat three groups of such actions.
