All of us are guilty of getting into a fitness slump at one point or another. But if you’ve been doing the same workout without results, it’s time to switch it up a bit.

Fortunately for you, the treadmill and elliptical are not the only cardio equipment out there. . In fact, there are quite a few cardio machines and fitness programs gathering dust in gyms that offer a workout as extreme as running.

Here are seven ways to shake up your slim-down.

Rowing Machine

A rower is a kick-butt cardio machine that mimics the motion of rowing across water.

If you will need to lose a few pounds, this is the machine for you. Not only does this piece of cardio equipment burn calories, but it also strengthens every major muscle group except for your pecs.

You can burn 600 calories an hour or more with the rowing machine–that’s comparable to running

VersaClimber

This is 1 piece of gear that shouldn’t be placed in the corner. Not familiar with the name? Having a versa climber, you stand upright and you use your arms and legs to simulate climbing. It is a total-body exercise because you have to use your body to pull against gravity.

The great part about it is that it is functional, a bit difficult at times and can help you burn off more calories than an elliptical or treadmill any day, as long as you put in the job.

The Cable Machine

The cable machine is one of the most overlooked pieces of equipment at the fitness center because exercisers often don’t know how to use it. All they have to learn is the way to set the cables and they can do a full-body work out utilizing this machine alone. If you want to build great abs and burn off love handles, use this machine to do wood-chop exercises.”

Away from wood chops, you can do chest presses, lat pull downs, rows, squats, military presses and deadlifts using cables. Not certain how to get started? Ask a trainer at your gym to show you the ropes.

Ski Machines

If you have ever spent an afternoon gliding through a snow-covered forest, you already know that cross-country skiing is an amazing fat-burner.

Also called cross-country skiers or skiers, ski machines can burn between 400 to 600 calories an hour, generally based upon your level of exertion.

These machines work both the upper and lower body, while maintaining your body aligned the right way for the best results.

StepMill

There’s an exceptional reason why walking up a few flights of stairs can leave you a bit tire –it’s a killer workout. Especially if those stairs not appear to end, as they do on the StepMill, a cardio machine that has a brief, revolving staircase that resembles climbing real stairs.

More then anything, it really works the butt and gets your heart rate up, plus it’s easy on your joints, noting you can burn somewhere between 500 and 700-plus calories an hour.
