Carry a sandbag to the top of a 40-60m hill, perform 10 Sandbag Back Squats and then carry the sandbag back down to the bottom of the hill. Dump the sandbag and repeat the hill sprint, remembering to do your squats at the top of the hill. Repeat this process until you have completed 10 hill sprints (5 loaded and 5 unloaded).
Men aim for a 30kg sandbag; women aim for 15kg.
Record your time.
