 Some health clubs offer a kind of exercise called anti-gravity yoga. When I first saw people hanging upside down from hammocks and calling it yoga, I kind of thought they were crazy. But it ended up being a lot of fun and just the swinging and it felt very playful. Yoga student Marie Bice says anti-gravity yoga has been good for her. But I don't have a lot of flexibility in my back and doing this work has really helped with that. Heather Blair is an anti-gravity yoga trainer. You actually have spinal decompression so when you're upside down your vertebrae actually open up so that the space in between the vertebrae opens naturally and gently. This is Chris Meyerhan's first class in anti-gravity yoga. I would like increased flexibility of course. I'm a guy, a runner, so my hamstrings are very tight. Instructor Heather Blair says a lot goes into the workout. Anti-gravity yoga is a combination of Pilates, a little bit of yoga, aerial arts and suspension training. So it's not just yoga. You literally could be of any fitness level. You can have injuries. It doesn't matter how old you are, anyone can take the class. Christopher Harrison is a dancer, choreographer and gymnast. He created anti-gravity yoga. I created it so even my mother can do it. Chris Meyerhan's was surprised at the effort required to do it. I had no idea that it was that much work. Christopher Harrison says yoga philosophy is still at the center of anti-gravity yoga. You can expect still to be studying yoga because it is a practice of awareness of body, mind and spirit. As with traditional yoga, classes end with meditation. I'm Christopher Cruz.
