To take this aid seriously, you need to disregard the joke about them elsewhere on this site. They are light buoyant material and are placed between your thighs for arms only swimming. They are not only great for developing your shoulder/arm strength but since your legs are immobilised and supported, they help you to think about and focus on head/body position and hand/arm placement in the water. Use a pull buoy if you are have a tough time breathing and/or can only swim short distances.
If you notice you are able to pull much faster than you can swim because the buoy elevates your legs into a streamlined position without any effort, then you need to re-evaluate your body position to reduce the drag from your legs during regular swimming.
For developing upper body strength and correct hand positioning, consider using hand paddles at the same time. With hand paddles however, do not grip the edges (keep your elbows high to prevent your hands slipping in the water) and build up gradually so as to minimise stress to your shoulders which can lead to injury. Make sure your paddles have holes to let the water pass through to minimise the stress on the shoulders and to let you feel the water. |
