Power Tow

This one is pretty self-explanatory. Start with a big-diameter soft rope. (Try a marine supply store for the best selection.) Then just wrap around your waist and get your partner to give you some smooth, appropriate resistance. You can tow straight ahead, but it's better to get your partner moving left to right. This forces the action into the frontal plane and makes things more interesting. Power your way across the park, switch roles and return the favor.
