Material and build - Made from high-elasticity TPE for good stretch performance and durability - Resistant to deformation and tearing, designed for repeated use Product features - Includes a resistance tube for versatile hand and forearm positioning exercises - Exercises can be performed vertically, horizontally, and diagonally - Ergonomic design and practical for swimming training sessions Function and benefits - The tension cord mimics resistance and movement of swimming, allowing you to train as if you were in the pool - Helps develop arm and shoulder strength without necessarily entering the water - Compared with standard stretch bands, it provides a constant, uniform resistance at every stretch to maintain the correct tension throughout each movement Use scenarios - Dry-land swim warm-up or strength routine: use the tension cord to simulate swimming strokes and prepare the arms for in-water training - In-pool strength training: use the resistance tube to perform targeted vertical, horizontal, and diagonal arm exercises while swimming - Rehabilitation and conditioning: controlled, consistent resistance to build arm and shoulder strength and flexibility without reliance on pool water Compatibility and care - Suitable for swimming training needs and general upper-body conditioning - Regular use with care will help maintain performance and longevity of the elastic components Notes - Designed as a compact training device to support swimmers at different levels - Provides a practical alternative to traditional resistance bands by delivering uniform resistance through each stretch
