Like a Football sled during two-a-days, Pax 1 assumes the Bear Crawl position while Pax 2 provides resistance to Pax 1's shoulders and resists their forward progress for a pre-determined distance. Then FlapJack. Another advantage of this exercise is that P2 can provide encouragement/motivation into P1's ear directly. MumbleChatter rises as resistance increases reciprocally. As developed in F3Nolensville.
