Regardless of what it is, you’ve probably got some sore muscles and aching joints that are reminding you of your hard work. Now you’re trying to figure out what to do so you can get back to moving around the house normally and not like the mummy just awoken from a 1000 year sleep. You could take some ibuprofen, do some stretching, light cardio, or sit in your chair contemplating why you signed up for all that to begin with. Or how about you strip down to your underwear, put on a pair of gloves, heavy socks, and something to cover your ears. Then stand in a giant freezer where the temperature is between -130 and -200 degrees for two to four minutes.
