Aerobic and anaerobic exercise can increase bone density, the details are as follows: First, aerobic exercise: mainly including running, elliptical training, jump rope, swimming, can significantly increase muscle strength and intensity, improve blood circulation and improve bone density. Second, anaerobic exercise: including barbells, dumbbells, weighted squats, high pull-down, dumbbell flying bird, etc., such exercises can make the muscle strength increased significantly. The increased muscle strength will pull the bones, stimulating significant improvement in bone density, but also help to correct severe osteoporosis. Therefore, the combination of the above two exercises can lead to a significant increase in bone density and avoid serious osteoporosis as well as fractures.
