Product Description

The RX4405 (APEX 2) is a self-powered endless incline training machine engineered for elite-level performance in a compact, space-efficient design. Featuring a multi-angle endless climbing tread and a progressive resistance mechanism, it delivers intense, low-impact training that builds strength, endurance, and power simultaneously. Integrated rotating base wheels make repositioning effortless, even in tight training spaces.

Designed to pair seamlessly with Ropeflex attachable endless rope trainers—such as the RX2100—the RX4405 transforms into a full-body conditioning system. Trusted by the military, fire departments, and police forces, it’s built to meet the demands of real-world training environments.

Like its larger counterpart, the RX4400 (APEX), the RX4405 redefines what a workout can be. Ropeflex’s proven progressive resistance technology is combined with the cardiovascular challenge of incline treadmill training to deliver ergonomic, natural movement patterns suitable for beginners through elite athletes. From steel hill walking (scrambling) to continuous resistance climbing, the RX4405 provides a safe, low-impact experience—yet delivers up to three times the effectiveness of traditional cardio and resistance training combined.
