REVOLUTIONISE THE WAY YOU TRAIN.

The TRNR X31 Resistance System, brings you a more efficient, varied, and safer workout - anywhere, anytime. Stronger, more defined arms, legs, pecs, abs, glutes, and back muscles have never been more achievable with this unique system that rivals an entire gym arsenal - despite fitting into a small bag. The progressive resistance throughout the entire range of motion maximises your results whilst being gentle on your joints. The Stackable Clip System enables you to mix up your routine and stay motivated. Select your favourite gym and Pilates exercises from the poster included and stack or remove resistance (3.4 kg up to 68.6 kg) to suit your personal needs. The door and outdoor anchors open a world of exercise possibilities by letting you move in any direction.  Setup is quick and easy - all you need is a door or a fixed object like a bench, tree, or pole. Switching from upper to lower body workouts only takes seconds by swapping the handles for the ankle straps.
