Wind-Relieving Asana
Thought fiber was the only natural remedy for expelling excess gas? Think again: this series of yoga postures assumed in asana-based classes assists air in exiting your digestive tract—in a room full of people. The motions involve lying flat on your back and pulling your left, right or both knees into your tensed stomach, squeezing out the stale air or, in instructor's lingo, engaging your abdominal region to assist with elimination. The poses are also said to enhance supine strength and flexibility, making them optimal for those with both bad backs and Metamucil in their pantries (read: old people). "It could certainly be helpful with some individuals in terms of [their] low backs," says Bryant. "But the whole flatulence aspect—I'm not so sure that there's a great deal of physiological support for that being a need."
The verdict: Group flatu-fitness? We'll pass.
