I think Marnie has a great concept for some amazing health benefits and increasing strength and balance of the body. What attracted me to come to the Tough lotus studio was my desire to do supported inversions to relieve back pain. I have been to about 4 classes now and am really starting to "get it". I am on a 5 class pass from groupon and am considering buying her 10 class package next.
I think the value of her ariel fitness comes once you attend several classes regularly over a period of at least two weeks. That increases your likeliness to get the most benefits from the experience. I have done ariel yoga in the past but this is a bit different. I like the tough lotus class for the challenge but then I like the balanced yoga for the longer stretching. I thought i was in good shape until Marnie asked us to do "handstand pushups".
My back always feels 10x better after i leave. However, my biggest hope is to gain increased neuromuscular activity for my little tiny stabilizer muscles. It feels great to finally work that small stuff you rarely do in the gym with free weights. The tension relief from decompression of the spine is the icing on the cake for me! It might look like "yoga" but if you do it often enough you'll discover the difference.
I commend Marnie for teaching so many classes a day. Props to doing it on your own girl :)
