Evidence has shown that weightlifting two or three times a week appear to stimulate bone formation. It is believed that the forces of muscle pulling against bone triggers the development. People of any age can benefit from strength training because bone density can actually increase and not just slow its loss.
If you think that weight lifting is only for men then you need to think again. A year long study has demonstrated that postmenopausal women who participated in strength training actually increased their spinal bone mass by nine percent, while those who didn’t experienced a decrease in bone density.
Other exercises like cycling and swimming doesn’t promote bone formation as effectively because minerals, including calcium are actually lost at an enormous rate during hours of sweating.
Strength training has also been found to improve your balance. Muscle strength, stronger bones and better balance are three good reasons to take up weight training to increase your longevity.
