I rug burned the bottoms of my feet.
Went to put on my running shoes and realized I had a problem.
I have always worked out bare foot - helps build up your foot muscles, strengthens ankles, makes you work harder to balance/engage core more....it's just what I have always done.
Doing Insanity Max Cardio Circuits.... bare foot.... on carpet = rug burned feet.
The take away from this??
1. A new way to measure my efforts : If I don't end up with rug burned feet after doing Max workouts I didnt' move fast enough.
2. Wear shoes, stupid!!
