Adjustable Silicone Finger Strength Trainer

A grip trainer works the closing motion. Almost nothing works the opening motion, which is where most hand weakness actually sits.

• Trains extension, not just flexion — the muscles a standard grip ring never touches
• Five resistance levels from 10lb to 75lb, colour coded so you can see where you are
• Independent finger cups so one weak finger is not carried by the other three
• Silicone, quiet and pocketable — usable at a desk without announcing it

10lb, 20lb, 40lb, 60lb and 75lb. Spare parts sold separately. Not a medical device.
