I purchased an underwater video camera to help with my swimming. It is turning out to be a great purchase...these can be had for $150 or so, and well worth the money in my opinion.
Amongst my many swimming flaws, I noticed that when I kick my legs look like they are flailing everywhere. Any suggestions to help me tighten up my kick? I understand that when I put on my wet suit I kick a lot less, but I want to be able to swim well without my wet suit.
