I've started swimming with fins. Boy does it make a difference. First off, it makes you swim faster because you're pushing more water away. I timed it the other day and to swim 1 mile (72 laps) without fins it takes me 50 minutes. To swim 1 mile with fins, it takes me between 35-40 minutes; however, when swimming with the fins, it works your legs more.
I read online though that you don't want to become "fin dependent" because then when you go to swim without fins, like in a triathlon, you're not going to do very well because you're so used to swimming with fins. So, I only swim with fins every other day. I really enjoy it. Now I just need to get my own fins.
