Overview
This FitBeast set pairs four silicone finger exercisers rated 3, 7, 9 and 11 lbs so each finger, or the whole hand, can be trained at its own resistance. It ships with a carrying bag and is built for dexterity and recovery work rather than heavy strength training.
Because each piece targets a specific resistance level, the set works as a progression tool rather than a single fixed-difficulty gripper. It is aimed at rehab, musicians and everyday hand stiffness, not at building maximum grip strength the way a single high-resistance trainer would.
- Four resistance levels: 3, 7, 9 and 11 lbs
- Trains individual fingers or the full hand
- Soft silicone grips for repeated daily use
- Includes a carrying bag for travel
Who it's for
Musicians, climbers and anyone doing hand physical therapy will get the most from the individual-finger training here. It is a poor fit for someone with notably small or large hands, since one reviewer found the pinky piece ran too wide.
What buyers say
From Amazon customer reviews.
Reviewers report relief from arthritis stiffness using the lighter pieces, a physical therapist recommending it for finger strengthening, and a professional musician noting improved forearm and finger independence. One reviewer with larger hands found the pinky piece a bit narrow to reach comfortably, and another said the set didn't feel as durable or sturdy as hoped.
Strengths and trade-offs
Drawn from this product's published specifications.
- Four resistance levels give a clear path to progress on
- Silicone grips stay comfortable through repeated daily use
- Trains individual fingers, not just the whole hand at once
- Compact enough to carry in a pocket or the included bag
- Sizing runs large for smaller hands, per at least one reviewer
- One reviewer felt it lacked a sturdy, durable feel
Performance notes
Each finger can be pressed individually against its own resistance level, or the whole hand can work through a comprehensive squeeze, with soft silicone grips meant to reduce strain over repeated sessions.

Is this meant for hand rehabilitation?
