This is a leg burner!!
Load the sled to between 30-50kg.
Start with 12 body weight squats to box (either low, medium, or high depending on your flexibility).
Set timer for 1 minute and see how many sled push lengths you can complete. Once timer stops round to the nearest length or half length.
Immediately finish with 12 body weight squats to box.
Record your distance and sled weight on the challenge wall. Please remember to unload your weights when completed.
