Jacobs Ladder 2 (JL2) – Scientifically Proven Low-Impact Climber
The Jacobs Ladder 2 (JL2) is a compact, high-performance cardio machine designed for low-impact, high-intensity training. Used by professional athletes, personal trainers, and rehab centers, JL2 provides a superior climbing workout with reduced strain on joints. Backed by research from Louisiana State University’s School of Kinesiology, this machine burns more calories at a lower perceived exertion rate than treadmills.
The self-paced design allows users to train at their own intensity level, while the climbing movement activates the entire posterior chain. Whether you're targeting fat loss, endurance, or rehabilitation, the JL2 is a compact and effective solution that fits into any training environment.
