WEST ALLIS, Wis. (CBS 58) -- A homegrown football player has a training program that's helping to slow the symptoms of people who have Parkinson’s disease. 

Darrell Jack is the owner of Fast Fitness in West Allis. The former UW-Whitewater middle linebacker opened the facility after working as a physical trainer. But after a friend was diagnosed with Parkinson’s disease Jack realized he had an opportunity to help. Fast Fitness now participates in the national Rock Steady Boxing program offering specialized boxing classes for people fighting Parkinson’s.

On CBS 58 Sunday Morning, Brendan Cullerton visited Rock Steady Boxing, the first gym in the area dedicated to the fight against Parkinson’s.
