@boomloverI'm tired after exercising for the first time in months.
To further explain, my dad and younger siblings go to a martial arts school that I used to do as well before high school and college. The classes are in the afternoon/night, but there's also an adult Kickboxing class on weekday mornings that my dad attends. Well my car needed several things fixed, so earlier today I dropped it off at the auto shop and got a ride with my dad to the martial arts school since he was going there anyways. I haven't really been in those classes regularly since maybe 2010 and I haven't really worked out in months. But I was bored and on an impulse joined in on the kickboxing class. So now I'm covered in dried sweat, and my back/shoulders/thighs are sore. And I kind of pulled one of my groin muscles.
