A couple of month's ago, Men's Health asked Alwyn Cosgrove —one of the world's top trainers—to create a cutting-edge fat loss program for Men's Health. And, of course, he obliged. But a curious thing: One of the workouts in the plan featured just two exercises.
That's right: When asked to create a super-effective, calorie-torching routine, Cosgrove gave us a workout that had readers do only a dumbbell swing and a squat thrust. This confused some folks, who wondered, "How can you lose fat with just two exercises?"
Here's how it works: You do 15 repetitions of the kettlebell swing (you can also use a dumbbell for this), followed immediately by 15 reps of the squat thrust. (See below for descriptions of both exercises.) Then, without resting, do another 14 reps of the swing and another 14 reps of the squat thrust. Continue this pattern until you complete only one rep of each exercise. This is called a countdown workout.
Sure, that's just two exercises, but do the math: If you complete the entire routine—from 15 down to one— you'll do 120 repetitions of each exercise. That's 240 repetitions. And these aren't just any exercises: They're movements that challenge your entire body.
They're also done at a fast pace. On average, it'll only take you about three seconds per rep. So you'll do those 240 reps in just 12 minutes or so. That'll light your muscles on fire and have you gasping for air (in a good way).
If you think that sounds too easy or too fast, I suggest you try it. You may find you can't even finish. But that's OK—you can just start with a lower number of reps, like eight, and work your way up as you improve your fitness. (In fact, I recommend this strategy.) If you want an even greater challenge, you can always take a breather and repeat the routine.
Remember: Whether you're running or lifting, your muscles require energy to help you move. And this workout forces more of your muscles into action than you'd ever use while jogging for the same duration. It'll also boost your metabolism for hours after your workout.
An important note: This isn't a complete workout program, but it is a great routine that you can do almost anywhere, anytime. And it's a fantastic substitute for 15 minutes on the treadmill.
Kettlebell (or Dumbbell) Swing
Bend at your hips, and hold a kettlebell (or dumbbbell) with both hands at arm’s length in front of you. Now, rock back slightly and “hike” the kettlebell between your legs. Then squeeze your glutes, thrust your hips forward forcefully, and swing the weight to shoulder height. Allow momentum to swing the weight—you're not trying to actively lift it with your arms. Reverse the movement, so that you swing the kettlebell between your legs again. Make sure you don't round your lower back at any time; it should stay naturally arched when you bend at your hips. Continue to swing back and forth.
Stand with your feet slightly wider than shoulder-width apart. Bending at your hips and knees, squat down and lower your body until you can place your hands on the floor. Kick your legs backward—into a pushup position—and then immediately reverse the move and quickly stand up from the squat. That's one rep. To make the exercise even more challenging, you can jump up from the squat instead of simply standing up quickly.
