FitBeast Grip Strengthener Forearm Hand Grips Strengthener Kit 5 Pack Adjustable Resistance Black Review (2026)

Who this kit is aimed at

This kit is built for pickleball players who want to train grip and forearm strength off the court rather than relying only on paddle time to build it, since a firmer grip can help control the paddle on hard volleys and fast exchanges at the net. Because the kit bundles five different tools rather than a single gripper, it also suits players recovering from a minor hand or wrist issue who want a gentler finger stretcher or stress ball option alongside a heavier adjustable gripper. It is not aimed at players looking for a quick fix, since grip training of any kind takes weeks of consistent use before players typically notice a real difference in paddle control.

What comes in the kit

The set includes one adjustable hand grip strengthener rated from 22 to 132 pounds of resistance, a finger exerciser rated at 4 pounds of resistance per finger, a light-resistance finger stretcher band, a grip ring rated at 50 pounds of resistance, a stress relief ball at a medium resistance level, a carrying bag and an instruction manual. That spread covers the adjustable gripper for building raw hand strength, the finger exerciser and stretcher band for finger dexterity and the muscles that oppose gripping, and the stress ball for lighter recovery-style squeezing. FitBeast backs the kit with an 18-month warranty and a 90-day return window if a buyer is not satisfied.

Building it into a routine

Because the adjustable gripper's resistance can be dialed up as strength improves, players can start light and increase the setting over weeks rather than being stuck with a single fixed resistance level. The finger stretcher band is meant to balance out gripping work by training the opposing extensor muscles, which matters because grip training that only targets the flexor muscles used to squeeze can contribute to overuse issues like tennis elbow if it is not balanced with other movement. A short daily or every-other-day routine with the kit is more realistic than occasional long sessions, since consistency over weeks is what produces a noticeable change in grip endurance during matches.

Trade-offs against a single gripper

FLYFE's 2-pack gripper focuses purely on the adjustable squeeze exercise with a built-in rep counter, which some players may prefer if they only want one tool rather than a five-piece kit to manage. WATMAID offers a similarly bundled 5-piece kit at a comparable resistance range, so FitBeast is not the only option in this bundled format. Because grip kits like this train the muscles used to squeeze a paddle rather than the wrist extension muscles used to control it through a swing, players chasing all-around forearm strength may still want to pair this kit with broader wrist and forearm exercises rather than treating it as a complete forearm program on its own.

Verdict and who should pick something else

For a player who wants an affordable, varied set of grip tools to build strength gradually between pickleball sessions, this FitBeast kit is a solid pick and matches the site's own score of 8.8 out of 10. Anyone who only wants one simple adjustable gripper rather than five separate tools may prefer a single-item product instead of managing a full kit. Players with existing tennis elbow or forearm pain should start light and consider checking with a physical therapist before adding resistance training, since overtraining the forearm can aggravate that kind of injury rather than help it.
