Yoga is everywhere. It's been a staple for flexibility and strength. The origin is unknown but it's estimated that yogis have been practicing for 5000 years. People have been doing the same asanas and vinyasas since the 1960's when a modern version of yoga was introduced via television and gained more widespread visibility. Add VHS distribution in the 80's and you've now created a pretty good following.
Inversion aids have been around for decades. They were flimsy and unstable but mostly effective if you were willing to give it a try. It wasn't until Lucas Rockwood developed an improved version in 2007 that inversions would get the attention they deserved.
Overall fitness consists of push, pull, and hold. Mat yoga offers plenty of push and hold. Unfortunately it lacks the ability to improve your pull and grip strength which is absolutely fundamental in our daily lives.
Practicing just once or twice a week, the combination of Yoga Trapeze and simple gravity can improve your own pushing, pulling, holding, body twists, back bends, forward bends and more.
