Just wondering how many people on here are looking to go PJ, BUD/S, Coast Guard, etc. I never got the chance but I would have loved to try out for PJs.
I do, every freaking day. Well, besides rest days. I also go to a masters swim class twice a week, to do drills to practice/improve my form. That's great, but I really love the FFluid workouts, they're so much more intense and so much better (I find) for the fitness/work capacity/underwater confidence. FFluid is built with military application in mind, and I think it works pretty well.
I use both FF's and a custom twist of my own, to prepare me for SERE. My swimming and water con have gone through the roof, a big improvement from not even being able to swim nine months ago.
I just joined and plan to use it to improve my swimming skills. Plan on X-training to SERE and a friend of mine is going to try for Combat Weather. This site should help us both. Already has. Also use fatal fitness.
Hopefully the setup here is helpful to you all. Trying to hit that sweet spot between work capacity (intervals, etc.), watercon, and mechanics to maximize efficiency.
