Start designing your very own resistance gym with the X-Heavy TRNR Strength Tube X. Made for resistance stacking that suit your personal needs, it features heavy-duty carabiners and multi-dipped natural rubber latex for optimal durability. Strategically placed at the core of the resistance tube, our innovative string ensures that your Strength Tube X cannot be extended past its maximum stretching capacity, preventing it from snapping prematurely. The X-Heavy level is specifically designed for pure power (combined strength and speed), body sculpting, and significant muscle mass gain through high-intensity workouts that target fast-twitch muscle fibers.

Please note: the other TRNR X Series components (Strength Handles X, Ankle Straps X, Strength Bar X, Door Anchor X and Outdoor Anchor X) to complete your resistance gym are sold separately.
