PRESLEY combines running with sled push and sled pull. Pick a moderate to heavy weight for the sleds, and make sure that the weight for sled push is heavier than for sled pull. Key to this workout is how good you can pace the run part. Use the first round, to find a comfortable tempo and try to maintain this for the entire 4 rounds. The time cap for PRESLEY is 80 minutes.
Scaling: You can scale PRESLEY by decreasing the time cap from 80 to 40 minutes, along with lighter weights for sled push and pull.
