Option #2: AMRAP bodyweight cardio pyramid
Remember the pyramid workouts from week two, where you started with a certain number of repetitions per exercise, then reduced the number of repetitions by one on each subsequent round? That's how this AMRAP is going to work. You'll set your timer for 12 minutes, and start each exercise with 10 reps, working your way down the pyramid as far as you can before time expires. Make note of what round you make it to. You'll rest for two minutes, then start the second 12-minute AMRAP, again starting with 10 reps for each exercise.
See how many rounds of all three exercises you can make it through following pyramid repetitions -- do 10 reps of each exercise, then nine of each, going through the circuit counting down until you reach one. You have 12 minutes to get through as many rounds as you can.
