Dual-Flow Resistance. Breathing is a full cycle, so training only one side of it is only half a workout.
- Inhale resistance challenges the muscles that pull air into your lungs.
- Exhale resistance builds control by resisting the breath on its way out.
Independent in and out dials. Each direction has its own dial, so you can set a heavier inhale and a lighter exhale, or the other way round, depending on what you’re training.
8 progressive levels. Without progression, breathing muscles stop being challenged as they adapt. Eight steps per side mean there’s always a next level to work towards.
