Swim fins can enhance your leg's muscular endurance. As a result of increased resistance, you can correct the wrong swimming posture of the leg and effectively train the lower part of the body.
- Increased resistance:
Fins can increase the area of contact with water during kicking and conducting resistance training. With high-intensity water kicking, heart rhythm will be improved significantly. On top of this, it can be extra training for the thigh and hip muscle strength too.
- Muscle training:
Medium-to-strong strength training in thighs and abdomen.
Pro-tips when shopping for swimming fins:
The hardness of silicone-made fins is very important. If the flippers are too hard, it may cause an ankle sprain.
- Length of fins:
Short fins ensure an ideal kicking frequency, which greatly improves cardiovascular function compared to long blades.
However, long fins help you to go further with each kick in the water as compared to short fins. So all in all, it depends on what you're looking for!
