Working in pairs, each pair has a "Pet Rock" with which to look after during the workout. Your "Pet Rock" is either a 15kg/20kg Weight Plate.
Your "Pet Rock" is NOT allowed to touch the ground during the entire workout. So while one partner is performing the workout the other is holding onto their "Pet Rock", until they swap over. The "Pet Rock" holder must be standing with the "Pet Rock", you may NOT sit down with it.
For Time Complete With Your Partner:
100 Thrusters 40/30kg
100 Knees To Elbows
100 Double Unders
1000m Run (with your Pet)
