I am a 46 year old newly minted purple belt, with a body that has been through over 20 years of active duty time in the military. I have been doing 45 min sessions of elements before nightly jiu jitsu practice and it is AWESOME. I feel like my body flows way better, it is not a magical elixir but I feel way better rolling with my training partners that are usually 10 -30 years younger than me. I have trained since I was teenager in weightlifting and exercise and I feel that this is by far one of the best. The follow along format and ability to decide to do 15-45 sessions is great to always be able to squeeze in training everyday. Also the slow progression really sneaks up on building your skill. An example of this is working on stalls in the frog, a little everyday, I tried just to see what my yoga crow looked like and it was CRAZY easy for me. Highly recommend
