If you practice boxing with dumbbells, it is recommended not to exceed 10 kg, and the basic strength must be 60 kg bench press and 100 kg squat.
This will exercise the speed, explosiveness and endurance of boxing without affecting your footwork.
Too heavy dumbbells will deform the movements in the process of practicing boxing, which is easy to fatigue, which is not conducive to endurance training, and will also cause damage to shoulder blades and elbows.
The boxing speed dumbbell of boxing champion Hoya is only 6- 10 pound.
If you want to exercise your basic strength, add 30-50 kilograms of professional dumbbells or barbells.
I practice dumbbells at a speed of 9 Jin. If you feel bad for a long time, the main scapula injury is relatively large.
I also configured 20 kilograms of dumbbells to do lateral deltoid exercises, and 30 kilograms of dumbbells to practice various basic strengths and girth.
In addition, I also equipped a 50 kg barbell of 1.2 m, mainly to exercise the strength of lower limbs.
If you are 13 years old, it is not recommended to practice heavy weights, because heavy weights develop horizontally, and you still have room to grow taller.
