Science Museum Talking Strength Ball

The top-selling strength ball has been given an all new functional twist. It talks, lights up and can be programmed to fit in with your training schedule. Pick from speed and endurance modes to strengthen your forearm muscles and see how many revs you can build with your wrists.

When the revs build, the torque does as well to make it even more challenging. The colour will change at programmed revolutions or at your personal best and it will verbally communicate your progress. - A.D.
