Weight Training for Stronger Bones Bone-density loss can begin
as early as your 20s, when calcium and phosphate, which help
form bones in childhood, can start to be reabsorbed by the body.
Without preventive measures, the reabsorption process speeds up
after midlife, creating fragile, more easily fractured bones. "A
simple weight-bearing exercise like walking can slow the rate of
bone-mineral loss," says James D. Lolis, MD, associate chief of
geriatrics at North Shore–Long Island Jewish Health System in
New York. "Even the most frail person can benefit from a
personalized regimen," whether it's walking, yoga, or using free
weights. Getting enough vitamin D and calcium is also crucial,
he adds, and for a serious problem, bone-building medications
are another good option.
