The best workouts don't just get your body going—they challenge your brain too. Keep your body and mind guessing with back-to-back strength and cardio intervals in this challenging HIIT workout from Sarah Kusch, a Los Angeles-based personal trainer. The magic of this high-intensity interval training workout is in the way Kusch designed it; the optimized interval blocks will enable your body to burn calories post-workout by entering into a state of EPOC: excess post-exercise oxygen consumption or the afterburn effect. (ICYMI, that's not the only benefit of doing a high-intensity interval training—or HIIT—workout.)
The dynamic cardio moves will increase your agility and coordination while the strength exercises build muscle and endurance. The result: a total-body burn in just about 30 minutes. (And there's more where that came from. Next up, try Kusch's workout to improve your balance or her calorie-burning cardio abs workout.)
You'll need: a set of dumbbells and an exercise mat for this class.
How it works: Follow Kusch through the 5-minute dynamic warm-up, 24-minute HIIT workout, and 5-minute mobility and static stretch cool down. (Seriously, don't skip the cool-down.)
