Spirit i-Strength Biceps Curl/Triceps Extension

The Spirit Fitness i-Strength Biceps Curl / Triceps Extension is a smart, commercial-grade arm machine designed to deliver precise, effective upper-body training. Combining advanced electronic resistance with a dual-function design, it allows users to train the biceps and triceps with improved control, comfort, and consistency.  Built for a wide range of users, the  Spirit  i-Strength Biceps Curl / Triceps Extension  includes four dynamic training modes—Pure, Eccentric, Isokinetic, and Elastic—to support diverse training styles and performance goals. The electronic resistance range of 15 to 190 lb (6.8 to 86.2 kg) ensures the machine is suitable for everyone from beginners to experienced lifters.

An angled arm pad helps reduce shoulder involvement to keep the focus on the working muscles, while the adjustable, pivoting curl/extension bar accommodates different forearm lengths for a smoother, more natural movement pattern. The padded, adjustable seat further supports ergonomic elbow alignment and training comfort. A touchscreen console with built-in Wi-Fi provides a connected training experience, delivering real-time feedback and seamless software updates. Finished with a heavy-gauge steel frame and commercial-grade components, the  Spirit Fitness i-Strength Biceps Curl / Triceps Extension  is engineered for long-term durability in demanding gym environments.
