How exactly did Henry Cavill attain his Superman body? Hours and hours at the gym. In a recent article by Men's Health, they revealed an added secret as to how Cavill sculpted his body to aptly portray the Man of Steel. In addition to a regular workout regimen, Cavill added a little extra push to his body called the "Tailpipe" method. The Tailpipe is a circuit training exercises developed by Mark Jones, the owner of Gym Jones situated in Salt Lake City. Jones was the trainer responsible for sculpting the Spartan bodies of the cast of 300. The Tailpipe method incorporates high-intensity training with rest and recovery in its circuit; both training and recovery aspects are extremely important facets of the workout.

The Tailpipe method is hardcore, but simple. After your typical workout, perform 25 reps of these exercises in a circuit. Make sure to rest and take 8 deep breaths through your nose in between exercises. Do as many sets as you can. All you need is a regular dumbbell or kettle bell. Approximately 16kg would do just fine for intermediate trainers. Here are the exercises:

1. Goblet Squat (w/ kettle bell/dumbbell)

While in a standing upright position with your feet perfectly square with your shoulders, grab the weights and hold them out in front of your chest with your elbows pointing down, and fingers pointing upward. You should be cupping the weight, with your arms and hands imitating the shape of a goblet. While maintaining a naturally arched back, perform a squat by bending your knees and lowering your body as far as you can before rising back returning to your primary position. That's 1 rep. Perform 25 reps.

Take 8 deep breaths through your nose. Avoid gasping. Move on to the next exercise immediately after.

2. Kettle bell Swing

Bend at your hips and hold a kettlebell or dumbbell with both hands at arm's length down in front of you. 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. Reverse the move between your legs, and keep swinging. Make sure you don't stress out your back by bending it in awkward positions as you are swinging.

Perform 25 reps of these, take your 8 deep breaths and then move on.

3. Squat Thrusts

Stand with your feet slightly beyond shoulder-width apart. Bending at your hips and knees, squat 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 1 rep. To add to the challenge, add a pushup as you go down, and jump up from the squat instead of standing up.

25 reps. 8 deep breaths. Next.

4. Jumping Jacks

Seems easy enough. Jump up while extending your legs outward away from your body and exploding your arms upward. Jump again while bringing your legs back together and bringing your arms back down. That's 1 rep. Do 25.

You're done with 1 set! Now go and start getting ready for that next set. Don't stop until you're Superman.
