The so-called 60% to 80% load, for example, you can lift 10 kilograms of dumbbells with great strength, then the dumbbell you choose is best in the range of 6 kilograms to 8 kilograms. This is the best choice. Of course, dumbbells are generally divided into light dumbbells and heavy dumbbells. The weight of light dumbbells is generally six, eight, twelve and sixteen pounds, in pounds. A kilo is equal to less than a kilo. The weight of heavy dumbbells is generally ten, fifteen or thirty kilograms. You can make a choice according to your actual situation.
Dumbbell is a kind of equipment suitable for exercise at home, which can reduce fat. The most important thing is that when it moves, the equipment will not make a sound and will not disturb your neighbors. If you want to gain muscle, my personal advice is to exercise six to twelve times in each group, five to eight groups a day, two to three minutes apart. Not too fast. If you want to lose fat, each group will do it fifteen to twenty-five times, with an interval of one to two minutes. The number of groups is up to you. Listening to some music when you like sports can relax yourself very well.
The way to exercise can also be decided according to your own preferences. But the weight of the equipment is best to go to the gym and ask the fitness instructor, who will give you more professional guidance.
