To strengthen bones, we’ve always heard that weight-bearing and high-impact exercises (like running and lifting weights) are best. This leaves many people assuming that their low-impact workouts aren’t doing much to improve bone strength. Swimming has long been touted as a low-impact exercise, one that’s easier on the body and good for individuals with joint pain.

However, a recent study from Israel’s Wingate Institute in Netanya indicates that women who frequently swim laps have greater leg bone mass than women who don’t swim at all.

Action Sparked: While weight-bearing exercises are the best way to strengthen your bones, swimming is another option, especially for obese exercisers who experience pain and difficulty moving. Try adding a few laps to your regular routine to relieve boredom, and to surprise your muscles…and bones!

Time Involved: At least 20 minutes

Body Benefit: Stronger heart, lungs, muscles and bones
