CLARK is a sole bodyweight workout that includes burpee broad jumps and running*. Each round of Burpee Broad Jumps, follows a 200m run. In the first round you do 10 Burpee Broad Jumps followed by a 200m run. In the second round you do 9 Burpee Broad Jumps followed by 200m of running. This framework continues until you reach Round 10.
*You can substitute running by estimating your run times and then do e.g. skipping, jumping jacks or mountain climbers.
Scaling: You can scale CLARK by skipping every other round and reducing the rounds from 10 to 5 (10-8-6-4-2).
