The Stark Series Back Extension has a walk-in design with adjustable back rollers, allowing the exerciser to freely choose the range of motion. At the same time, the Stark Series optimizes the pivot point of the motion arm to connect it with the main body of the equipment, improving stability and durability.

Structure Strengthen
Structurally enhances the stability of the movement arm, allowing the exerciser to better use the lever principle for training without any safety concerns.

Elevated Footrest
To ensure proper knee/hip alignment and back stabilization, the footrest is positioned to elevate the user's knees to the correct angle.

Resistance Design
The movement arm is designed to ensure that smooth resistance is felt through the entire range of motion, eliminating common dead spots found in similar machines.

Based on the mature manufacturing process and production experience of PowerMax Fitness in strength training equipment, the Stark Series came into being. In addition to inheriting the all-metal design of the Fusion Series, the series has added aluminum alloy components for the first time, combined with one-piece bend flat oval tubes, which greatly improves the structure and durability. The split-type motion arms design allows users to train only one side independently; the upgraded and optimized motion trajectory achieves advanced biomechanics. Because of these, it can be named as Stark Series in PowerMax Fitness.
