have one of the original motion masters..simply an awesome training tool..great for beginners to experienced fighters...the most versital piece of equipment we have at the gym

I use this bag everyday for all of my fighters, and in my submission and mma classes. It has helped more pro fighters and new students with their ground transitions and ground and pound game than I can say...it is truely a 'must have' for anyone who wants to clearly get better with their endurance and movement!!! I swear! Erik P.
