Pair up with a partner and stand side by side, with your inner legs touching. Tie your inner ankles together with a soft strap, scarf, or rope, snug enough to hold but not so tight that it cuts off circulation. Wrap your inner arms around each other's waist or shoulders for extra support and to help you move in sync. Line up at the starting mark together with the other pairs, ready to move forward on the starting signal. Step off together with your tied legs moving as one, calling out a simple rhythm together to help you stay coordinated. Take shorter, quicker steps rather than long strides, since overreaching is what usually causes pairs to trip and fall. The first pair to cross the finish line together, without separating their tied legs, wins.
