What it is
A palm-sized electronic grip tester. No handle, no springs. You squeeze the shell and the display holds the highest reading until you reset it. Fits in the small pocket of a gym bag. The display reads in kilograms. Multiply by 2.2 for pounds.
Spec
- Range 0–180 kg (0–396 lb), display in kg
- Peak-hold reading · count mode for reps
- USB-C rechargeable
- 3 × 2.4 in. (7.5 × 6 cm), one size
How it's used
- Arm at your side, elbow straight. One squeeze, 3 seconds, full effort. Read the peak.
- Do the other hand. Write both numbers down.
- Retest every 30 days, same hand, same time of day. Before your session, not after.
Not a medical device. Readings are for comparing your own sessions, not for clinical measurement. Numbers between two units can differ; compare against yourself on the same unit.
