Do it right

The cossack squat simultaneously strengthens and stretches the groin. It also works the glutes and hamstrings.

This exercise is not for beginners, though. If you're trying it for the first time, proceed slowly, hold onto a well-anchored support for balance and don't bend very deeply. Cossack squats can also be hard on the knees, so if you've got knee problems you should probably avoid them.

To do the cossack squat, stand with your feet apart in a wide stance, then slowly sit back onto your right heel while your left foot flexes to face the ceiling (or the sky). Pause for a moment, then rotate to the other side, keeping your back straight and your arms in front to counterbalance your weight. Do 10 to 15 repetitions. (Each side counts as one.)
