Here's a fun thing we did as a cool down at Camp Gladiator on Wednesday. We had dumbbells in our hands and worked on shoulders. Every time the lady says "up" you raise them above your head, and every time she says "down" you lower them to about ear level. Shoulders were on f*cking fire by the end of the song. But you could also do it with push ups or squats and get a nice little burn effect happening.
