Fibra is a strand-based resistance system. Each Fibra arm holds up to 24 individual strands within a fixed steel frame. Add or remove strands in seconds to dial resistance up or down. No slack at the start of the movement. No dead zones through the range of motion.

Use one arm or two. One arm gives you the finest progression, one strand at a time. Two arms increase resistance in pairs, two strands per adjustment. Both setups give you precise control for unilateral and bilateral movements.

Each arm weighs less than 2 kg, so you can move it with one hand, take it from room to room, or pack it for travel.

The same anchor profile mounts to almost any solid structure. A door, tree, rack, rig, pole, or footplate. Your training system goes wherever you do.
