How to use them
The fins are attached to the feet. There are several lengths to choose from, depending on how you will use them.
The short ones are ideal for swimming in a pool. They allow you to work on speed and stroke frequency. Longer ones are more suited to apnea or open water. They offer greater resistance and are often used for strength training.
Fins can also be more or less rigid. Rigids ones require more effort and work the muscles more, while softer ones are better suited to working on technique.
Drills with fins
Here are a few exercises to improve your stroke and technique, using fins.
Improve your technique
Exercice : Do kicks with the fins, concentrating on a continuous, fluid leg movement. Take your time to focus on the movements and stay sheathed as much as possible. Your arms are not moving, either using a board or extended in front of you with a snorkel.
Goal : Fins help maintain a horizontal, hydrodynamic body position in the water. Fins amplify technical errors, allowing you to correct poor posture thanks to their extra buoyancy.
Special drills
Exercice 1 : Swim full stroke using fins to work the whole body.
Exercice 2 : Combine the use of fins with a kickboard to focus on leg work.
Exercice 3 : Dofreestyle catch drill using fins. One arm stays out in front while the other performs a freestyle stroke. This helps you work on your arm-leg coordination.
