This circuit workout brings a special focus on your cardio and arms. Now that you’re pretty far into the Eternal Beach-Body Plan—it’s the fifth workout in Phase III, and the twenty-eighth overall—you’re well-prepared for this cardio-arms tandem.
As this circuit is designed, your bigger muscles (like legs and core) won’t get too gassed, meaning that you can still grind through moves like burpees and lunges. Your arms will take the brunt of some exercises, and then benefit from brief recovery phases while you’re jumping rope or doing jumping jacks.
This workout is done in two parts. The first part (exercises 1-10) is a circuit. You’ll do as many rounds of that circuit as you can in 40 minutes. Once the 40 minutes are up, you’ll move on to the second part of the workout (exercises 11 and 12), which is done in conventional straight sets.
