Why flywheel training

This is why athletes train with a flywheel

You pull, the flywheel spins up. On the way back you have to brake it – and that lowering phase is where most strength is built. Physiotherapists call it eccentric overload. You will simply feel every muscle working, all the way through the movement.

Read the full explanation

Stronger in less time

Both the lifting and the lowering phase count, so every rep does more work.

Always your level

The resistance follows your own force. Gentle enough for rehab, tough enough for athletes.

Fewer injuries

Training the lowering phase makes muscles and tendons more resilient.

A full gym in one device

Squats, rows, presses and rotations – on a wall, a rack or the floor.
