I've been doing planks regularly (using wii fit) to help with core strength.
But I was having difficulty...one of my feet has developed plantar fasciitis, pain along the bottom of the foot, and the tip-toe position doesn't help with the pain.
Today I had a brainwave...what if I wear cycling shoes? And, problem solved. I just hope I don't damage the cycling shoes.
ANYWAY. Anyone have other suggestions for core exercises that would be easy on feet and knees?
