How it works

Compression and cooling do the hard part.

Two technologies create the adaptation of intense training at low effort - delivered through a guided, 21-minute interval protocol. You stay seated, cool, and comfortable while your body does the work of a far harder workout.

The core mechanism

Two technologies. One effect.

Compression and cooling work together to signal intense effort to the body - without actually imposing it.

Compression cuffs fitted to a user's arms and legs during a Vasper session

Compression

Soft, large-surface cuffs apply gentle compression to your arms and legs while you move at low intensity. This builds metabolite concentration quickly and recruits fast-twitch muscle fibers - signaling the body as though it had just finished a far more intense workout, and triggering a systemic recovery response. Because the cuffs slow venous return without restricting arterial flow, the sensation stays comfortable and accessible at any age.

Why it matters: the strength and recovery signal of intense training - at a fraction of the mechanical load.

Active liquid cooling integrated into the Vasper seat and cuffs

Cooling

Active liquid cooling runs continuously through the seat and cuffs. Staying cool keeps blood and oxygen available to your working muscles instead of diverting to the skin - so you can sustain output longer, the session feels easier, and sweating is dramatically reduced or eliminated. The experience stays comfortable from the first minute to the last.

Why it matters: more usable output with far less strain - and you finish refreshed, not drenched.

The protocol · Pillar 03

Interval training

Compression and cooling don't work in isolation - they're delivered through a calibrated, low-intensity interval protocol. Short, guided cycles of effort and recovery are what link the two technologies and drive the circulation and blood-oxygen delivery your muscles rely on for output and recovery. It's the protocol that makes 21 minutes enough.

Why it matters: the delivery system that turns two technologies into one complete, time-efficient session.

What a session looks like

21 minutes, start to finish.

  1. Settle in ~2 min

    You sit into the recumbent system and a specialist fits the cooling cuffs to your arms and legs. No special clothing and no warm-up required.

  2. The protocol ~17 min

    You follow a guided, low-intensity interval protocol - pedaling and pulling at a comfortable effort while compression and cooling do the heavy lifting.

  3. Cool finish ~2 min

    The protocol winds down. Because you stayed cool throughout, most users finish without breaking a heavy sweat.

  4. Back to your day

    You step off energized rather than depleted - ready to train again, get back to work, or compete.
