If I could only do one workout for the rest of my life, it would be strength training—for sure. Apart from making you feel like a badass and sculpting a sexy bod, hundreds of studies have shown that strength training boosts your metabolism and has a positive impact on fat loss and calorie burning. This means big changes in your body composition!

Another super power of strength-training exercises is that they can double as a cardio workout. By performing strength-based moves that boost your heart rate, like the ones in this week's workout, you can get your sweat on and get out of the gym in record time. How's that for multitasking?

The workout: Complete three circuits of all five exercises below in order without resting between moves. For the first circuit, complete 10 reps of each move. Complete 12 reps for the second circuit and 15 reps for the third. Find a sustainable pace that keeps your heart rate up but allows you to finish the entire workout. Breakout your '80s-style sweatband because you're about to heat things up!

See the workout in its entirety in the Pinterest-friendly graphic below, then scroll further down the page for a play-by-play of each move.

Hold a 35- or 45-pound barbell with your hands slightly wider than shoulder-width apart. Place the barbell directly over your head with your arms fully extended but not locked (A). Stand with feet shoulder-distance apart, and lower your hips into a squat. Lower until the tops of your thighs are almost parallel to the floor and your hips are slightly higher than your knees (B). Pause, then push through your heels to return to the standing position. Keep your arms perpendicular to the floor. That’s one rep. Repeat the move for the recommended reps without lowering the bar from above your head.

Stop when your chest is four inches from the bar (B). Lower back down to the starting position. That’s one rep. Without releasing, complete the recommended number of reps for each set.
