Two weeks ago I started doing the “plank core yoga stance” every morning to strengthen my core muscles. I am still only able to hold the pose for about a minute, but I think it’s working. Today I was in 1870s garb, full corset from 9 – 6. My main core is not sore at all. The only part that is a wee sore is in the middle of my upper back, right where the top of the corset hits my back. Odd. But I feel good!!! Healthy and ready for a full summer of living history! Woot!
