Exercising muscles will not make people grow taller, and teenagers also need proper muscle exercise to promote their development. Only when you are too young (such as a child) should you pay attention to the amount and intensity of exercise. At this age, you should not focus on the development of muscles and strength, but on flexibility, coordination, balance and technical exercise.
Strength training subjects such as dumbbell training will not affect height. The weightlifters you usually see are short, because in order to get good grades, some short and strong people will be selected in the selection of athletes.
Another fact is that scientific moderate-intensity strength training for teenagers is of great benefit to their development; Training can not only make teenagers' muscles strong, but also make them psychologically strong, which can make them more accustomed to bearing pressure. Of course, dumbbell training can be used as a part of moderate-intensity strength training for teenagers.
If you can't grow any longer, you can carve your body shape with dumbbells to improve your strength or carry out functional training. If you are in adolescence, you should pay attention to the counterweight of dumbbells, and it is not advisable to use too heavy dumbbells for training. The total weight of a pair of dumbbells should be controlled below half of its own weight. And it is best not to exercise for more than 45 minutes at a time.
Arm bars can only exercise some muscles, so it is better to buy dumbbells for exercise.
According to China people's regular physique and exercise intensity, and considering the stage of increasing dumbbell fitness intensity in the future, the following dumbbell combinations are formulated:
Height 1.60m, weight 60kg-25kg；;
Height 1.70m combination of 70kg and 30kg;
Height 1.80m, weight 80kg-35kg；;
Height 1.90m, weight 95kg-45kg combination.
In bodybuilding theory, RM is used to indicate the maximum number of repetitions that a load can do continuously. For example, an exerciser can only lift a heavy object five times in a row, so the heavy object is 5RM. If the purpose of your dumbbell fitness is to gain muscle, do dumbbell movements from 8RM to 12RM every day, with 3 to 8 groups of 8 to12 in each group; If the purpose of your dumbbell fitness is to keep fit, do the related dumbbell movements 15RM to 20RM every day, and do 5-6 groups for each movement, each group 1520.
