Place the back of your forearm on a table or leg. Your palm should be facing up and your hand should be aligned with your arm. Gently place the dumbbell with the hand holding the dumbbell, then slowly lower the dumbbell to the limit, and then forcibly restore the wrist to the initial position, and keep the peak contraction for two to three seconds. Each wrist should do four or five groups twice a week, each time 10 or 15 times.
Newcomers are often impatient at the beginning of fitness, thinking that they should work hard to achieve some effect quickly. Only those fitness programs with high difficulty and large amount of training have the best effect, and those seemingly simple or even easy movements are sneered at. This includes warm-up exercises.
Although warm-up time will not directly bring obvious exercise effect, low-intensity aerobic warm-up for about 15 minutes can quickly raise the body temperature and adjust the body to a state suitable for exercise. After the body temperature rises, the muscles in all parts of the body can be stretched in time. If you stretch your muscles without warm-up, it is easy to cause muscle and ligament strain. The purpose of fitness is to improve physical function. If you get injured because of fitness, you will lose more than you gain.
