Partner A will hold a plank first. Keep back straight, hips level and feet a few inches apart.

Partner B will stand at A’s feet and jump laterally over A’s ankles, careful to avoid A. As soon as B has jumped to one side, immediately jump back to the other side and repeat for 30 seconds. Then, switch roles.

Repeat, this time rotating the other direction to ensure both sides of the body are exercised.

Partners A and B will sit facing each other, with toes touching in sit-up position and one partner holding a medicine ball. At the same time, both partners will lay back and complete a sit-up. Once at center, Partner A will pass the medicine ball to Partner B and both partners will complete a sit-up again. Repeat.
