The unit allows users to change resistance quickly by adding or removing springs, enabling a range of intensity from light to firm in a single device. Key benefits Adjustable resistance: Four included springs allow stepwise resistance changes so users can progress gradually or tailor difficulty to specific exercises. Targeted upper body work: Designed to engage forearms, wrists, elbows, and upper arms through twisting and rotational movements. Simple and fast setup: Springs attach and detach quickly, making it easy to switch resistance between sets or users. Portable and spaceefficient: Compact size fits into a gym bag or drawer for use at home, at the office, or on the go. Durable construction for regular use: Built to withstand repeated spring tension and everyday handling. Features and attributes Function: Provides rotational resistance through a multispring mechanism to train twisting and gripping motions. Resistance system: Fourspring configuration for adjustable load. Add springs to increase resistance, remove springs to decrease resistance. Compatibility: Suitable for a wide range of users and fitness levels who want to work on arm strength, endurance, or coordination. Can be used with standard tabletop or lap support, depending on exercise. Size and portability: Compact footprint for easy storage and transport. Designed for standalone use without the need for additional equipment. Materials and durability: Constructed for repeated spring tension cycles and daily handling. Components are selected to maintain consistent resistance and longterm use.

Adjust springs between sets to increase or decrease difficulty as needed. Practical use scenarios Home strength sessions: Use the trainer for short, focused upper body routines in small spaces to add rotational exercises to a home workout. Desk breaks and mobility warmups: Keep the device at a workstation to perform a few sets during breaks, helping maintain wrist and forearm activation without long equipment setup. Sportspecific warmup or skill prep: Include rotational wrist and forearm work as part of a warmup routine for activities that require grip and twisting motions. What makes this product stand out Fourspring adjustable system provides clear, maintainable steps in resistance without the need for multiple devices. Portable, easytoconfigure design supports quick transitions between intensities and users. Focused on rotational and griprelated movement patterns that complement broader upper body training.
