My favorite workout is probably running because I can do it alone to just get away, or I can take the kids in the stroller for a little extra workout and still be able to spend time with them. Plus it just makes me feel good. But...now that I have read about the rope in the backyard - I may just have to have my husband put one up for us. That seems like it would be challenging yet fun. Of course, I have a feeling my two sons would also find a way to make trouble out of it!
