NoTrax T30 General Purpose Rubber Competitor Safety/Anti-Fatigue Mat, for Wet Areas, 3′ Width x 5′ Length x 1/2″ Thickness, Black
I purchased this on amazon.com for the kitchen to help with back pain while standing for long periods of time preparing foods. It cushions your feet absorbing the tension from the weight of your body as you stand still or move.
It was a little much for a kitchen that small, so I moved it out to the foyer carpet. Now that it’s on carpet it’s creates even more cushion, so I decided to use it for an exercise mat when I do squats or marching in place or running in place. It’s particularly effective with the running.
Since I have such a messed up spine with vertebrae practically resting on top of each other, running even with legs kept fairly low was impossible due to the jolts to the vertebrae and spine. This works and I’m enjoying that small new freedom.
