The pull buoy is placed between your thighs to keep your hips and legs raised to the surface of the water. A bit like a wetsuit does except only on the lower half of your body. Using this wonderful piece of kit means you don’t kick, and for all of those swimmers out there who don’t like kicking, I include me in that, it is heaven! However, if you do find yourself kicking when your pull buoy is in, try tying your legs together at the ankles with a piece of cord or old inner tubes, no I’m not kidding! Then you can start seeing what a true weakling you really are!
I love my pull buoy and that’s just what it is, even the tying up bit is kind of fun! But having such an array of swim toys to choose from it just makes swimming, for me at least, much more interesting and fun. As I have said before, using them correctly and not relying on them is what ultimately will help you to become a more efficient and stronger swimmer.
