Welcome to the halfway point—and phase two of the program. Joel dials-up the intensity with more reps of more exercises to give you even greater results—starting with a lower-body workout that will set your legs on fire.

It's time to build and burn with an upper-body workout that hits your chest and back with classic strength training before hammering it with calorie-incinerating HIIT. It's tough, but so are you. Go crush it.

Give this key muscle group the attention it deserves to broaden your back, boost your strength, and reinforce two of your body's most important (and injury-prone) joints. Follow Joel's cues to lift safely and optimize your results.
