The other half of grip. Everything you do in the gym closes your hand. This opens it. Five silicone finger caps on a resistance ball — extend, spread, squeeze, repeat.

What it is

A silicone ball with finger sleeves for extension and abduction work. The muscles on the back of the forearm get almost nothing from lifting; this is where they get it.

Spec

  • Food-grade silicone, wipes clean
  • Fits most hand sizes (caps stretch)
  • Weighs less than a phone

How it's used

  1. Fingers in the caps. Open the hand wide against the caps — 15 reps.
  2. Squeeze the ball — 15 reps.
  3. Do it while the kettle boils. That's the whole routine.

Not a medical device. If you are injured, talk to a professional before adding any tool to your routine.
