The TRNR Strength Tube is the perfect addition to any training arsenal. Resistance is recommended for active individuals who want to build strength and improve joint stabilisation all at the same time. Incorporating Safety String Innovation, the Strength Tube lets you work out with peace of mind, knowing that it cannot be overextended and result in snapping. The door anchor included also means greater exercise possibilities as it allows you to work against the resistance in any direction. Colour varies by strength. 2=light, 4=heavy.
