Theyre extremely effective at targeting key muscle groups to upgrade your performance in the pool. These bands are a must-have for anyone looking to take their pool workouts to the next level! This trainer forces you to improve your technique by giving you the opportunity to practice all sorts of strokes day in, day out. Technique is such a vital part of being a great swimmer, which is why we created the Resistance Swimming Trainer. These resistance bands are engineered to target key muscle groups that are directly correlated with swim speed and endurance. The added resistance allows you to overload your muscles resulting in increased strength over time. The waist belt is designed with high-grade neoprene which allows the belt to form to any body type. On top of that, the velcro strap lets you tighten or loosen the belt to help you find the ideal fit. Our resistance bands provide the perfect amount of resistance for you to be able to swim in place, meaning you can train at home or your local pool. Our 4-meter (13ft) cord can reach just about anywhere, allowing for use with any pool.
