Using light weights, our routines are centered around slow, methodical movements. A recent study in the Journal of Sports Medicine and Physical Fitness found that low-weight, high-repetition resistance training is especially effective for increasing bone mineral density in adults. Participants in the study experienced up to 8 percent bone density increases in their arms, pelvis, spine, and legs.
