Strength training aids stroke-weakened hands, arms

Another benefit of training.

Strength training improves hand grip and arm function in people who have suffered a stroke without causing increased muscle spasticity or pain, according to combined data from multiple studies.

Of course, it is possible that many of the stroke victims would not have had them if they were not overweight/obese.

In any event, once you got it, training can apparently help.

Still, it is better not to have the stroke.
