1, for the first time, in order to correct the boxing and make it more standard, many athletes hold it in their hands with light dumbbells, such as one kilogram, so that the powerful movements of muscles will not float, and they can better understand the strength and precise control of muscles.
2. To practice explosive force, push for 20 or 10 second at the limit speed with 40% or 60% of the maximum load. The explosive force is not only the contraction force of muscle, but also related to the ability of nerve excitability to mobilize muscle fibers, so it should be short and precise.
3. Practice extreme strength or absolute strength, and use the heaviest dumbbell.
