I'm new to all this. I'm building my training up pretty well but swimming is my weak spot so I really need to concentrate on this. I need tips for my training, I've got access to one of these kind of pools
http://www.endlesspools.com, a resistance pool I think they're called as well. Would this help? I figured it would cut down the time I lose on turns. Has anyone used one for training?
Also, I'm worried about losing time during transitions.
One more thing, are swim caps compulsory?
