Arm Trainer inSPORTline Griphoop

The Arm Trainer inSPORTline Griphoop proves that even a compact fitness tool can seriously challenge your muscles. At first glance, it looks like a simple ring with a handle, but inside it delivers a dynamic workout that activates far more than just your grip. On top of that, it lights up during use and features an LED repetition counter, making every set more motivating and fun.

Small Tool, Big Results

The main magic of the inSPORTline Griphoop lies in its light-up 224.4 g rotating weight, which oscillates during movement and creates variable resistance. This forces your muscles to constantly react and stabilize the motion, engaging the fingers, palm, wrist, forearm, biceps, triceps, shoulders, chest, and upper back. Unlike traditional grip trainers, this isn’t just about squeezing—it’s a functional workout for the entire upper body.

More Exercises, More Muscle Engagement

Thanks to different arm positions and exercises outlined in the instructions, the inSPORTline Griphoop allows you to target specific muscle groups—from the arms and shoulders to the upper back. It supports coordination, shoulder joint stability, and helps improve overall movement control. A small training tool that can really do a lot.

Motivation with Every Rep

The LED repetition counter gives you instant feedback on your performance and motivates you to push a few reps further. The light-up weight not only looks great but also helps maintain a smooth rhythm and proper technique. The result is a workout that’s both effective and enjoyable.

Perfect Anywhere

Its compact size makes the inSPORTline Griphoop easy to take anywhere—home, work, or on the go. It’s suitable for athletes, recreational exercisers, and compensatory training. Just a few minutes a day provide your hands and arms with exactly the load they need.
