Learning: Create abbs by turn and twist. Also use your hands to keep distance to your partner.

Not just great idea to clean the tatami, but also get some great abbs. One partner stands and the other lays down on the floor with the belly on the tatami. The one standing should try to touch the other ones feet. (By running around the laying person.) To move quick and easy when you lay on the floor, make your back hollow and move your body with your hands.

Tip: No jumping just moving.
