Whereas the previous Phase I workouts were designed to burn fat and develop that baseline of physical ability, Phase II workouts incorporate fewer reps, longer rest times, and higher intensities. The shift will be gradual, though, which is why Workout 15 will still challenge you with 30-second rest periods and 10-rep sets. Consider this your preparation for the more difficult (and more complex) exercises of Phase II.
Do each exercise in straight sets; complete all sets of each exercise before moving on to the next.
Make sure you pay attention to the designated rest—30 seconds will go by fast, and you’ll be well served by tracking your rest periods on your watch or on a clock.
Because the rest periods are so short and the volume is so high, don’t be afraid to choose relatively light weights.
