Any guy who goes to the gym on a regular basis probably wonders, "What workout should I do?" more often than not.

But no matter what equipment you have available, from a fully stocked supergym to a pair of mismatched dumbbells in your garage, or nothing but your bodyweight alone, you can build muscle, lose fat, and sculpt the physique you've always wanted.

Well-rounded fitness means being both strong and conditioned, but a tight schedule usually causes either weights or cardio to get left out of your program. The answer is to combine them both in one densely packed circuit.

How it works

Although you’ll train for only a fraction of the time that most guys sweat it out in gyms, you won’t sacrifice big gains in this workout. The brisk pace will double as cardio, and the sequencing has another advantage as well—moving from smaller to larger muscle groups enhances the way your muscles are recruited, resulting in greater strength and muscle gains.

Directions

The workout is broken into six circuits. It may look long, but the whole routine will take only 20 minutes. Perform the circuits in order, repeating where noted. Your rest between exercises should be only as long as it takes to transition between moves. Repeat this workout up to four times a week on nonconsecutive days.
