I do a fitness class twice a week where we do similar exercises--planks, squats, all that. I'm sore EVERY SINGLE TIME!!! I swear sometimes it seems like I spend 4 out of 7 days in pain. Sometimes it's not much. Like the last couple days it was just my hamstrings. Last week they really did the abs and I swear I couldn't roll over in bed from Tuesday until Sunday. I've been doing these classes for about 9 months now. I am getting better at it, but sheesh, there are always ways to up the intensity and try to do better at them, so I'm always hurting.
