Jacobs Ladder JL2

The Jacobs Ladder JL2 is a compact version designed for home gyms where a full-size commercial Jacobs Ladder unit would not fit. It maintains the same continuous ladder-climbing motion but with a smaller footprint and lower height requirement than the commercial model found in gyms.

Unlike a stair climber, the Jacobs Ladder JL2 requires simultaneous upper and lower body engagement because users climb rotating rungs using both their arms and legs. This creates a higher-intensity, full-body cardiovascular workout that many users find more demanding than stair-only machines.

The Jacobs Ladder JL2 uses the company's continuous ladder format, where the belt speed is driven by the user's own climbing pace rather than a motor setting. The faster you climb, the faster the rungs rotate, and slowing down or stopping immediately slows or stops the belt.

The self-paced, full-body climbing motion makes the JL2 well suited to high-intensity interval training, as users can instantly ramp up speed by climbing harder and recover by slowing their pace. The simultaneous arm and leg engagement drives heart rate up quickly, making short intervals highly effective.
