Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD).
Ankle weights help with faster weight loss by burning 5 to 15 percent more calories than walking without weights. Weights provide a combination of cardiovascular and strength training, which help build muscle. Making your walking routine harder enables you to spend less time working out. The addition of ankle weights will help tone your calf, thigh and abdominal muscles, buttocks and the back of your legs.
Some of the replies claim that the difference in calories is negligible because you are only adding 10 lbs of weight, but it is important to remember that ankle weights are not passively carried near your center of gravity, but are taking advantage of the physics of rotational motion meaning that a small weight a long distance (about a meter) from the center of gravity increases the moment of inertia SIGNIFICANTLY, thus requiring much more work and burning many more calories.
