Cardiovascular exercise varies greatly from strength training. Instead of lifting heavy weights for a short amount of time, you move your body repetitively for an extended amount of time. Arc Trainers are treadmills are two types of cardio machines that have similarities and differences. Before engaging in a regular workout program, compare the two machines to learn which one will best suit your needs.
Features
The obvious difference between the Arc Trainer and treadmill is the way they look. An Arc Trainer has foot pedals that are elevated from the ground, and has hand-held poles. Treadmills have a flat belt with handrails along the top. Both machines have digital screens that give you your time, speed and distance as you work out.
Function
The Arc Trainer and treadmill are both operated from a standing position, but in a different way. To use the Arc Trainer, stand on the pedals and grasp the poles with your hands about chest high. Move your right arm and leg forward while simultaneously moving your left arm and leg backward. Quickly shift directions and continue to move back and forth for the duration of your workout. This machine automatically turns on once you start moving. The treadmill, however, needs to be turned on. Stand on the sides of the belt before you do this, then step onto it one foot at a time and start walking or running.
Adjustments
You have the option of making your workouts more intense by making certain adjustments. On the Arc Trainer, for example, you can change the resistance, incline or both at the same time. The treadmill allows you to change your speed and incline. All of these changes can be made by pressing the appropriate buttons on the console.
Muscle Utilization
When you walk or run on a treadmill, you predominately work the muscles in your lower body. The glutes, quadriceps, hamstrings, calves and tibialis anterior, or shin muscles, are examples. The Arc Trainer works these muscles, plus numerous muscles in the upper body, such as the pectorals, latissimus dorsi, triceps and biceps. The lats are the large muscles in the middle to upper back, the triceps are on the back of the arms and the biceps are on the front. Increase the workload on your muscles and make your workouts more challenging by increasing your resistance on the Arc Trainer and incline on the treadmill.
Impact
The Arc Trainer provides a no-impact workout, which can be beneficial if you have joint issues. The treadmill, however, does cause impact, especially if you are running. Keep in mind, though, that if you have osteoporosis, impact can actually be beneficial. Walking, for example, works directly on the bones in your legs, hips and lower spine to slow bone mineral loss, according to MayoClinic.com.
Benefits
Regular physical activity -- regardless of whether you use the Art Trainer or a treadmill -- increases good cholesterol, lowers blood pressure, and reduces weight and triglycerides, according to the American Heart Association. Aim for at least 30 minutes of exercise on most days of the week to reap these benefits, and combine exercise with a sensible diet.
