## Summary description

HMS Fitness EM03 is an adjustable grip strengthener designed for hand and forearm training. Finished in black and steel, it features plastic handles and a 580 mm width. The device provides variable resistance for strengthening grip, improving forearm endurance and rehabilitation exercises for athletes, fitness enthusiasts and physiotherapy use.

## Long description

HMS EM03 Black Steel is an adjustable grip strengthener intended for hand and forearm training. The device consists of two durable plastic handles connected by up to five steel springs; the unit has an overall width of 580 mm. Steel springs provide high tensile strength and allow the user to vary resistance by installing or removing individual springs. The construction is suitable for progressive strengthening, endurance work and targeted rehabilitation exercises for athletes and fitness users.
Advantages
The adjustable spring system enables stepwise resistance changes without tools, so the device can be adapted to different strength levels. Plastic handles deliver a secure, comfortable grip while the steel springs ensure durable, repeatable resistance. The 580 mm width provides stable hand placement and makes the device suitable for different hand sizes and exercise variations. The simple, robust design is low-maintenance and portable.
Suitable for
Improving grip strength and forearm endurance
Rehabilitation and physiotherapy exercises for wrist and hand recovery
Supplementary conditioning for climbers, racket sport players and weightlifters
General upper-body toning including arms, chest and back
Home workouts and portable strength sessions
Key specifications
Adjustable resistance via removable steel springs (up to 5 springs)
Durable steel springs with high tensile strength
Two ergonomic plastic handles for secure grip
Width: 580 mm
Compact, lightweight construction for portability
How to use
Hold the plastic handles with one or both hands and squeeze to contract the springs. Adjust resistance by removing or adding springs to match your current strength or rehabilitation stage. Perform controlled repetitions, focusing on full closure and slow release to train both concentric and eccentric muscle actions. For bilateral use, grip the device with both hands; for isolated forearm work, use one hand at a time. Inspect springs and handles before use and replace any worn components.
Usage recommendations
Begin with a low number of springs and gradually increase resistance as strength improves. For rehabilitation, follow a clinician’s guidance on repetitions and frequency. Include rest days for recovery and combine grip training with general forearm stretching to maintain flexibility. Store the device in a dry place to prevent corrosion of steel springs.
