As someone who has recovered from multiple shoulder surgeries and a Brazilian Jiu Jitsu player, I find the exercises here essential. I'm the smallest guy in my BJJ class at 130 lbs (61 kg) and I'm constantly fighting guys much bigger than me. One way I can overcome their strength is through flexibility, so all my joints are put under great stress, as they have to support my own weight and someone much larger. Many of the exercises on these DVDs are intended to protect you from these kinds of stresses, through the incremental controlled exposure to these the stressful movements, so that when you are put in these movements during training, your body will be familiar with the motion and more resistant to injury. The key here is control. I think it would be very easy to injure yourself by doing some of these exercises the wrong way. Maxwell repeatedly warns the viewer about respecting your pain threshold, but because he's in such good shape, the exercises sometimes look easy. So I highly recommend working yourself into some of the more exotic exercises rather slowly. After some cautious practice, when done correctly, these exercises are obviously beneficial to the body. You can get a sense of what's healthy and unhealthy movement in some of the more unusual ranges of motion. For someone who doesn't do any submission grappling, it's important to know that some of the movements are based off of submission holds (which he mentions) and the original intention of the holds is to destroy the joint. Anyone with grappling experience would know what is a safe range and an unsafe range, so please go very slowly. Once you develop a feel for this, the exercises are perfectly safe. He covers almost all movable joints from head to toe, and you also train coordination and balance. This is a very unique and beneficial series for most anyone, but particularly so for contact sports, especially wrestling and grappling. I highly recommend it.

I found this DVD set especially helpful for my upper body flexibility. I have been doing these exercises every morning for my neck, shoulders, and back. I am more flexible and less injury prone. This DVD set offers many exercises where you can select your own favorites and make a personal routine that suits you.
