So the goal is to carry an item for 50 metres, drop it down, pick it back up and walk back 50 metres. Keep going until you reach 1000Kg moved a distance of 50 metres.
It is important to remember to keep good form the whole time. Use your legs and hips to lift items off the ground, don’t round your back. Keep you back straight while walking, head up, shoulders back, and basically keep good posture. Bare feet is best, or vibrams.
