We hold no study, no EMG data and no comparison of any kind behind that. It is gone, and nothing equivalent has taken its place. What the ball does is give your forearm, wrist and grip something to resist.

This page no longer suggests the ball for recovery from anything.

We could not verify either against supplier documentation, and the supplier's own artwork disagrees with the speed figure that was on the page. Both have been removed rather than guessed at.

There is no basis for pairing those two things, so both halves of the sentence have gone.
