Here is another interesting research finding.

Daily squats reduce hip fracture in the elderly.

Walking alone does not benefit the hip’s weakest point.

Between the ages of 20 and 80 there is a 32% decline in bone mineral density at the weak point, the femoral neck. Squatting, stair climbing and jumping improve bone strength in this vulnerable area.

Start squatting.
