STOVALL PRODUCTS Adjustable Hand and Grip Strength Trainer MAX PRO 990, TensionLevel 5 LBS to 150 LBS, Steel Durable

Built for clinicians, athletes, and anyone rebuilding hand function, the MAX PRO 990 replaces flimsy plastic grippers with a rugged steel design and five selectable springs. Its wide handles accommodate larger hands and let you train all fingers and thumb comfortably while you progress through precise resistance steps.

How does this trainer support recovery after hand surgery or injury?

With gradual, repeatable resistance settings, the MAX PRO 990 lets you restart motion safely and rebuild strength one increment at a time. Its durable build gives therapists confidence for repeated clinical use and daily home programs.

• Adjustable resistance from 5 to 150 lbs in clear increments
• Five spring positions for controlled progression
• Wide handles reduce pressure on individual fingers
• All-steel frame withstands frequent, heavy use

What makes this better than basic plastic hand grippers?

Unlike small, brittle models, the MAX PRO 990 is constructed from steel and designed to fit the whole hand, not just a couple of fingers. That means longer lifespan, more even force distribution, and a grip path that lets you train more naturally.

• Rugged steel construction resists bending and breaking
• Larger handle geometry for full-hand engagement
• Progressive springs for measurable gains
• Portable but clinic-grade durability

Can athletes use it to improve sports performance?

Yes — climbers, racket players, paddlers and combat athletes use progressive grip training to increase endurance and peak force. The MAX PRO 990 supports both high-rep conditioning and heavy-strength sets thanks to its broad resistance range.

• Low setting for endurance and rehab reps (5–30 lbs)
• Mid range for functional sport strength (30–90 lbs)
• High range to build max grip force (90–150 lbs)
• Fits varied hand sizes for sport-specific grips

How portable and user-friendly is the device for everyday use?

The MAX PRO 990 is compact enough to keep in a gym bag, clinic drawer or on a desk, yet sturdy enough for repeated sessions. Changing resistance is straightforward, letting you move between rehab sets and performance work in seconds.

• Compact footprint for easy transport and storage
• Simple spring-change mechanism for quick adjustments
• Solid feel for confident single-handed use
• Suitable for home, clinic, and gym environments

Who is this for? The STOVALL MAX PRO 990 is aimed at physical therapists, sports medicine professionals, and serious athletes who need a durable, adjustable grip trainer. It also suits anyone recovering from hand or wrist issues, or people wanting to level up forearm and grip strength with a reliable, clinic-grade tool.
