A few of the exercises we did:
Squat Jump High Five
Plank Ball Pass
Beginning in a plank position, partners face each other and pass a medicine ball back and forth. Looks can be deceiving, as this is a challenging exercise requiring each person to maintain a stable plank position (keeping the glutes from sinking or lifting too high) for one full minute and move on command without collapsing.
First partners begin back-to-back with the objective of passing a dumbbell over his/her head to their opponent and the second partner passes the dumbbell back between their legs. Passing a dumbbell of any kind requires concentration to pull the belly button into the spine, while squeezing the glutes to keep the spine stabilized.
