Three days ago I made the mistake of doing about 40 situps and 25 pushups. My stomach is still so sore that it hurts to laugh and I have to get up from a sitting or lying position like an old man. And the area where one would normally expect to find their pectoral muscles is also very painful and sore. I seriously just had Thao give me a chest massage (ah, marriage!). I am a well-oiled machine, I will tell you that.
