Is Working Out on a Cross-Training Machine Aerobic Exercise?

May 26, 2011 | By Rick Rockwell

A cross-training machine, also called an elliptical trainer, is a low-impact exercise machine first marketed in the 1990s. It simulates walking or running and allows the user to exercise at different intensities and inclines. Some models work the upper body as well as the lower body, and the higher-end models allow you to program a workout with a specific goal, such as cardiovascular conditioning or fat burning. Most gyms have at least one of these machines, and many models are made for home gyms as well.

Aerobic Exercise

Aerobic exercise, also called cardiovascular exercise, is any exercise that challenges the heart and lungs. Examples of aerobic exercise are walking, jogging, rowing, swimming and cycling. Machines that simulate those movements, such as the exercise bike, treadmill and elliptical machine, provide the same aerobic benefits.

Pros

Cross trainers are easier on the knees, hips and back than other cardio machines, such as the treadmill, and they use more muscle groups. In addition to lower-body muscles such as the quadriceps and hamstrings, cross trainers also incorporate upper-body muscles such as the biceps, triceps and deltoids. Another benefit of the cross-training machine is that it is quieter than a treadmill, which can be a benefit for home use.

Cons

Injury may occur if the user falls off or uses more resistance than the knee joints can handle. Some machines use the momentum of the legs to power the arm handles, which negates the upper-body movements. This reduces the number of calories burned and precludes any upper-body strength-building benefits.

Caution

Always read the instruction manual or request a demonstration on proper use of the cross trainer. Never use a machine that is poorly maintained or visibly defective. If you're purchasing a machine for home use, try out several models to make sure the one you buy feels comfortable and fits your stride. If you experience dizziness, nausea or faintness while using the machine, stop immediately and seek medical attention. Never use more resistance than feels comfortable on your knee joints.
