It is good for girls to focus on equipment in strength training. Each device has instructions for use and an introduction to exercise muscle groups. Dumbbell barbells will properly practice the training of latissimus dorsi triceps and chest muscles. Connect the barbell with the empty bar and use a few kilograms of dumbbells. Specific actions include squatting on the bar, flexing and stretching of dumbbell triceps, barbell paddling, dumbbell flying birds and so on.
