As a SEAL hopeful, I found this DVD immensely helpful. Being a beginner swimmer, I was getting nowhere watching the short YouTube clip. The way this video broke down the stroke into simple steps and then put them all together made it easy for even me to learn. I recommend it to any other SEAL hopefuls.
I used to be an ocean lifeguard on the East Coast at Smith Point Park on Long Island back from 1978 to 1987. Now, as a 48 year old fitness swimmer, I bought this C/D out of curiousity and to see what the BUDS trainees trained with. As an ex-Air Force doctor, the background patriotic "liberty" music is never grating, but to the average person it may be distracting. This C/D is good to help one gain confidence and relaxation in the water, and I find it helps one's core immensely. It is an inexpensive way to learn a method of swimming that is great for cross training. Just don't think that this will help your cross-chest rescue technique.
Ok, I should have paid more attention, but this course is very specifically designed for Navy guys learning to pass the side-stroke test that's required for Seals. VERY specifically. Still, it's interesting and well-done instruction. Not the fitness-stroke I'd expected but a gliding-stroke with minimal arm and body movement. I can't review this without also mentioning that the background music is a MOST irritating and constantly repeating song. I appreciate that it's supposed to be inspiring and patriotic, but it's just awful. My future viewings will be with the mute button on. At least it was on sale.
