Fitness - 30 secs on/off

For fitness we picked partners and did a 30 secs on and 30 sec off rotation. I liked this fitness because I thought it was fun. Karyssa and I did everything for the whole 30 secs. We made sure both of us were doing it properly and for the full turn. I tried my best and put effort into this activity and felt really sore the next day. This is the type of fitness I would prefer.
