There are many dumbbell lifting methods, and you can practice biceps brachii, triceps brachii and deltoid muscle of shoulder. But whether you can lose weight doesn't depend on what kind of exercise you do. Simply put, losing weight is the energy intake every day.

Therefore, to lose weight, we must first control the amount of food. Only by eating less can exercise get twice the result with half the effort, but it should be based on our physical condition. Eat less, not less.

In addition, no matter what exercise can consume calories, aerobic exercise consumes more energy per unit time than strenuous anaerobic exercise. Therefore, walking and jogging can lose weight more than lifting dumbbells in the same time.
