In groups of 3, Lunge with a 30kg sandbag on shoulders for a total of 300m.
3 movements:
1) Lunge
2) Dumbell Swing - 15kg

Person A does max effort lunge with 30kg sandbag on shoulders. When Person A can't lunge anymore, then Person A drops the sandbag and runs back to the base. Whilst Person A lunging, Person B is doing Dumbell Swings and Person C is doing Toes Through Rings. Once Person A is back to base, everyone rotates stations - so Person C runs, picks up the sandbag and continues lunging for max effort. During this time, Person A is doing Dumbell Swings and Person B is doing Toes Through Rings. Rotate through each movement until sandbag has been lunged 300m.
