I went back to my first TKD class tonight. Luckily, Laurel & Mijung were there to help me through. I don't feel too bad tonight but we'll see how I feel in the morning. It felt more like a mental challenge than a physical one. We kicked up and down the room in complicated combinations of kicks that, as a black belt, I should be comfortable with but since I haven't gone in 3+ years I am quite rusty.
