One by one, watch those numbers add up
Keys Fitness Counter Hand Grips: The only handgrip with a built-in counter.
Likes: Watching the numbers on the counter change from 00 to 99 as you squeeze can be very motivating.
Dislikes: The hard-plastic handles can be uncomfortable after a while.

Taking a digital approach to fitness
Grip Master: This grip allows you to squeeze your fingers separately, as if you were playing a trumpet.
Likes: You can also work your fingers together, as with other types of handgrips. Different tensions are available: Black, red and blue correspond to hard, moderate and easiest. Comfortable palm-shaped rubber handle.
Price: $13.99. (800) 880-3427.
Thumbs up for building strength
Altus Ultimate Hand Workout: This handgrip looks like brass knuckles on a spring.
Likes: Works your thumb the best of all grips tested (others largely ignore it). Soft-plastic-covered finger grips are comfortable. You can increase the difficulty by moving all four fingers up one ring, with your index finger extended. Comes in a package that also includes an easy-to-squeeze, egg-shaped rubber ball and Z Grip, a plastic-coated spring shaped like a doubled Z.
Dislikes: May be too difficult for some people who have smaller hands or lack grip strength.
Price: $12.50. (800) 654-3955; www.altusathletic.com
A different spin on handgrip exercisers
TheraGrip: A handle with a gyroscope attached to the end.
Likes: A vigorous grip, wrist and forearm workout. You'll need to hold on tight; the gyroscopic action tends to yank the handle away. To start the scope, spin the rotor with one hand and twist the handle like a motorcycle throttle with the other hand.
Dislikes: Too noisy to do at your desk if you work in an office setting. Not especially relaxing.
