If you're looking for a creative way to challenge your muscles, try combining two old-school moves into one awesome new exercise.  

The lunge to pushup works a ton of calorie-torching muscles like your glutes, quads, abs, pecs, and shoulders at once, says David Jack, owner of ActivPrayer in Phoenix, Arizona, and creator of the Men’s Health 60-Day Transformation workout. 

Plus, you'll need athleticism, flexibility, balance, and coordination to seamlessly transition between the two moves. "It's a complex movement," he says. "Protect your lower back and knees by performing each rep slowly and with purpose."
