I have the Book COOL IMPOSSIBLE. I just cannot thank Eric for the foot strength exercises, especially, the Slant board. I started running at the age of 58 with some seriousness. I felt very awkward to be in the Group where the Team had to wait for me to catch up with them. In fact I was dragging the team. Slant board for 2 months as mentioned in the Book and Lo! the position had reversed- Literally. The ease, the push and the style- all too impressive for the inconspicuous & easily dismissed "little" exercises. Thanks Eric once again.
I do not need to over emphasize the benefits. Check it out yourselves.
