Stimulus and Strategy:
Today’s workout is a combination of strength, stamina, and cardiorespiratory endurance. Keep in mind that this workout is not only for time, but also for total reps of double-unders and burpees. The loading of the barbell should be heavy, but allow you to complete the set of 21 in 4 sets or less, while maintaining proper form. If you are struggling to maintain a neutral spine, reduce the loading. Expect your heart rate to be significantly elevated after the double-unders and burpees. Take a few breaths to get yourself set before picking up the heavy barbell.

Scaling:
Reduce the loading of the barbell.

To reduce the complexity of the double-unders, perform single-unders. For the burpees, perform up-downs.

In case of injury or limitation, perform sumo deadlifts with the barbell or a kettlebell. For the double-unders, perform lateral hops over a line or penguin taps. For the burpees, perform calories on any machine available.

Coaching cues:
On the burpees, focus on jumping your feet up to your hands and landing on your heels. Doing so reduces extra steps and distributes the load to the stronger muscles of the posterior chain.
