Grab a pair of pound weight plates and hold them together directly in front of your chest, smooth sides facing out. Spread your fingers wide on the plates. Squeeze the plates together as you press them forward until your arms are pointing straight out in front. Return the plates to your chest and repeat. Put the car in neutral and give it a shot. On a long, flat stretch of pavement, have a friend put a car in neutral. Stand behind the car and put your hands on the trunk about shoulder-width apart.

Awesome name for a double-duty move. Keeping your hips level as you row each dumbbell to your shoulder will tax your core while you train your lats. Assume a push-up position while holding a dumbbell in each hand directly below your shoulders. Your body should form a straight line from head to heels. Maintaining this body line, bend your elbows until your chest is between the dumbbells. Press back to start, then bend one elbow to row the weight up next to your rib cage. Return it to the floor, do another push-up and repeat on the other side.

As with the renegade row, this move engages your lats while you stabilize your core. Lie on your left side in a side-plank position facing a low cable pulley.

Prop yourself up on your left elbow with feet stacked and body forming a straight line from head to heels. Row the handle of the cable machine with your right arm until your hand is in line with your torso. Return the cable to start and repeat. Then switch sides and repeat. Placing weight on one side of an exercise means your core has to work to keep your body upright. Stand holding a dumbbell at your right side.

Take a large step forward with your left leg, lowering as you step until your knees both form degree angles. Press back to standing and repeat. For an added challenge, try moving the weight to your shoulder then straight overhead or to the other arm. Your core fires first in moves like these and stabilizes your torso to let you use the rest of your strength to do the move.

Lie on your back with arms at your sides, palms down, legs extended. Lift your legs perpendicular to the ground so the soles of your feet face the ceiling. Keeping your legs straight, lower your right leg until it hovers just a few inches off the ground. Your left leg should still be sticking straight up.

Return your right leg to the top, lower your left leg and repeat. It has to fire in all kinds of moves, especially squats. Throw in a row and, well…you get it. Stand facing a cable machine stack set at shoulder- or waist-height. Grab the handle with your left hand. Stand on your right leg with your knee slightly bent, your left leg trailing behind you.

Push your hips back to squat with your right leg. As you stand back up, bring your left leg forward so your knee is up in a marching position and row the cable to your side. Return to start, repeat and switch arms and legs. This move is pretty much the pinnacle of side-plank progressions. Lie on your right side, prop up on your right hand with your hand directly beneath your shoulder and arm straight.

Your feet should be stacked on top of each other, your body forming a straight line from head to heels. Extend your left arm so that your body forms a T. Maintaining this rigid body line, separate your legs, raising your left leg until your body forms a five-pointed star. Hold this position for as long as you can maintain a rigid torso.

Repeat on the other side. Stand with a staggered stance, your left leg slightly in front of your right. Grab the hammer with your left hand at the base of the handle and your right up closer to the head. As you bring the hammer up, your right hand should slide down to meet your left. Once you reach your shoulder, swing the hammer down and slam the tire. Repeat on the other side, with legs and hands switched. Balancing on a Swiss ball is tough enough.

Try maintaining perfect form while intentionally throwing your stability off. Prop yourself on a stability ball in plank position with your elbows on the ball, feet on the floor and body forming a straight line from head to feet. Maintain this rigid body line as you move your elbows beneath your shoulders to rotate the ball in a small counterclockwise circle beneath your chest. Talk about mimicking real life! Grab a heavy dumbbell and hold it at your side in one hand as you would a suitcase.

Walk forward while maintaining an erect posture and keeping your shoulders level. Stand with a loaded barbell at your feet. Bend forward at the waist, knees slightly bent and grab the bar with an overhand grip.

Roll the bar out, keeping your toes on the ground, until your body is straight in a full-extension position. Now use your core -- not your arms -- to pull the bar back toward your body and return to the bent-over position. Lifting your arm and opposite leg while maintaining core stability and keeping your hips level is tough enough.

The size of the ball is key. Lie facedown on a Swiss ball, with the ball under your belly button. The balls of your feet and your palms should be on the floor almost in a push-up position over the ball. Hold for a second, return to start and lift your right arm and left leg. Alternate in this way. In one study from , the jackknife was found to be the best core exercise for targeting the lower abs.

Start in push-up position with your shins on a Swiss ball. Without rounding your lower back, contract your abs and use your feet to pull the ball toward your chest by bending your knees. Pause before returning to the starting position. Perform a push-up, maintaining a straight body line, then repeat. This advanced take on the jackknife takes a ton of core control.

Without bending your knees, roll the Swiss ball toward your body by raising your hips as high as you can. Pause, then return the ball to the starting position. For best results concentrate on controlling the ball with your core, not your arms or legs. When you perform a push-up, your core maintains a rigid plank position. With your hands on a Swiss ball, assume a push-up position with your feet on the floor, hands directly beneath your shoulders and body forming a straight line from head to heels.

Bend your elbows, keeping them close to your sides, until your chest touches the ball. Press back to the start and repeat. Lie faceup on a Swiss ball with your upper back on the ball and feet on the floor, knees bent at 90 degrees. Your body should form a straight line from your head to knees. Hold a lightweight plate or medicine ball with straight arms directly over your chest. Brace your midsection and bring the weight to the left without bending your arms by twisting your core until your arms are parallel to the floor.

Keep your hips up as you move, but allow them to rotate. Twist back to start, then twist to the right. Continue in this way. Nick Tumminello, a strength coach in Fort Lauderdale, Florida, and owner of Performance University, uses this maneuver because it mimics the type of twisting our cores perform in sports. Stand with feet hip-width apart, your arms bent as your sides, forearms parallel to the floor. Without relying completely on your shoulders, rotate at the torso to move your hands left and right.

Move quickly as if you were sprinting. What makes this move tough? The get-up requires your whole body to keep that weight above your head while you get up and down. Hold a dumbbell in your right hand with your arm straight above you. Keeping your elbow locked and the weight above you at all times, move your legs and left arm underneath you to push yourself up. From here, stand up. Still keeping your right arm straight and the weight above you, reverse the motion to return to the starting position.

For best results, keep your core braced throughout the move. If you remove a leg from a table, it has trouble staying up. Remove two, more trouble. And the missing legs keep changing. Assume the classic push-up position: Raise your right arm and left leg simultaneously until your right elbow is next to your ear.

Your pelvis should not twist; the front of your pelvis should still face the floor. Hold your arm and leg in the air for a second, then return to start. Now lift your left arm and right leg. Hold for a second, return to start and repeat. Click the link below for a printable version of the "The 41 Hardest Core Exercises. Have you tried any of these moves? Have you mastered all 41?

The elliptical might just be the most used — and misused — piece of equipment at your gym. While the amount of calories you burn in any given elliptical workout depends on ramp height, resistance level and speed stride speed, you can burn usually burn about to calories in 30 minutes see the sidebar for more info.

And because your feet never leave the pedals, the elliptical provides a low-impact workout that is friendly to your joints and back, unlike a treadmill. The machine builds strength and muscle endurance in the quads, hamstrings, glutes and calves, but also works your arms, chest and back when you actively use the handles. The elliptical is a powerhouse among cardio equipment because it allows you to use a large amount of muscle.

There are plenty of reasons to hop on an elliptical, but here are just a few:. Thus, an elliptical workout is both quieter and more comfortable. To lose one pound of fat, you need to be in a caloric deficit of 3,, meaning you burn more calories than you consume. So depending on other factors, you can start to see small results within a week and more major changes within a month. If you do the same workout over and over, the body adapts to it. So even if your primary mode of cardio exercise is the elliptical, you'll want to beat the boredom and the workout plateaus by incorporating some of these other machines and cardio options into your routine.

Here are the pros and cons of each of the alternatives. As another low-impact cardio machine, the stationary bike also allows you to sit while you workout, helping you maintain your balance and making it ideal for those with joint or back pain. But while you can adjust the resistance, you can't adjust incline or use the handle bars as you would in an elliptical. Taking your bike outdoors has the advantage of real-world challenges that you can't control like you do at the gym.

There are hills and obstacles to take on, plus you have the added core stability challenge to make sure you stay on the bike. And overall, cycling is fairly low-impact. But again, beginners or those with joint issues should favor the elliptical, at least at first.

Though the elliptical is great for beginners because your body weight is fully supported by the machine, the treadmill has the potential to scorch more calories for advanced runners, depending on your speed and incline. Seasoned runners will likely favor the treadmill, only mixing in the elliptical for cross-training. And because your body weight isn't supported on a treadmill, you'll get a higher-impact workout and build more bone density.

However, the treadmill is solely a lower-body workout, while the elliptical features an upper-body component. Those who want a full-body cardio workout or those with joint issues should opt for the elliptical. While the elliptical does mimic some of the movements of running in a more low-impact manner, running outdoors gives your muscles especially your glutes, quads and calves more of a challenge, as you're not plodding along on a machine.

Plus, it means you're not tied to the gym. Unfortunately, it can be taxing on your ankles, knees and hips, so if you have injuries or weaknesses in any of these areas, stick to the elliptical. As long as you don't lean too heavily on the hand rails of the stair stepper, this machine can provide a great lower-body workout, targeting the glutes and quads even more than the elliptical.

But like most other cardio options, the elliptical is still your best bet for the lowest-impact workout. But if your goal is fat loss, the question isn't which machine will work best, it's which machine you'll work best on. Pick the option that you feel you can do the most fat-burning intervals on.

Or see below for fat-burning elliptical workouts. First, there are a few things you should keep in mind during every elliptical workout. Stand tall with correct posture, your head over your shoulders and your shoulders over your hips. To work the upper body, you must actively push and pull on the handles, not just hold on, says Johnson. But avoid grabbing the handlebars too tightly; doing so can fatigue the forearms and shoulders and tempt you to lean on the machine—a common mistake.
