Adjustable Hand Grip Kit for Strength and Rehab

The ZKFKJXOXO HB-1 kit provides five pieces of sports-medicine equipment designed for adjustable grip, finger, wrist and forearm training. It serves athletes, musicians, office workers and rehabilitation patients who need progressive resistance in a single portable package. The set includes a countable hand grip strengthener, a four-gear finger stretcher with wrist strap, a silicone grip ring and a textured stress ball.

Simple Setup with Counter and Strap

No assembly is required; each component is ready to use straight from the drawstring storage bag. The hand grip strengthener features a built-in counter that records repetitions so progress can be tracked without manual counting. The finger stretcher includes a wrist fixing strap to prevent the device from slipping during high-tension stretches. Resistance on both the grip strengthener and the finger stretcher is adjusted by selecting the desired gear or level before each session.

Mechanical Resistance Limits Portability

All resistance is generated by internal springs and silicone elasticity, so the maximum load is capped at the 560kg rating of the adjustable grip strengthener. Users seeking higher overload or electronic feedback will find the mechanical design restrictive. The compact bag holds every piece for gym, office or travel use, but the kit cannot replace heavy cable machines or digital dynamometers for advanced strength testing.

Questions about this item

How do I confirm the built-in counter on the 560kg adjustable grip strengthener is recording reps correctly after setup?

Squeeze the handle through a full range of motion; the counter increments once per completed repetition, letting you verify it tracks each rep accurately.

Which items come in the 5-pack kit and is anything else needed to start training?

The kit includes the adjustable hand grip strengthener with counter, a 4-gear finger stretcher with wrist strap, a silicone grip ring, a stress relief ball, and a drawstring storage bag — no extra purchases required.

Which tension gear on the 4-gear finger stretcher should I choose for my current finger strength?

Start on the lowest gear and progress to higher gears as flexibility improves; each gear increases resistance for gradual finger strengthening.
