This Week’s Defining Fitness (02-01-09)

Arc Trainer- The arc trainer is very similar to the elliptical trainer. To mount the arc trainer, hold on to the side handles, foot in each pedal and begin moving forward and back. Much like on the elliptical trainer, the arc trainer provides an excellent workout for those who have issues with their hips, knees or lower back. It’s important to remember when exercising on the arc trainer to keep your hips stationary. There are handles to hold on to beside you, in front of you, and below the screen. The handles below the screen have a built-in heart rate monitor, so by holding these handles you can view your heart rate on the screen. To intensify the workout, hold on to the handles and pump your arms as if you were running.

Cardiac Output- This is the volume of blood being pumped by the heart, in particular by a ventricle in a minute.

Cardiovascular training- Some people refer to it as aerobic exercise; some people even call it 'cardio' for short. This is exercise that involves the large muscles such as your legs and helps make your heart and lungs stronger. Regular cardiovascular exercise has the ability to lower blood pressure, burn calories and improve blood cholesterol levels.

Elliptical Trainers- Elliptical trainers combine the motions of a treadmill, stepper, ski machine and a bike in one non-impact, weight-bearing motion. Some on the market provide both forward and reverse motion to add variety. Total body elliptical trainers provide arm motion as well. Although you do use both upper and lower body motion in a total body unit, if you work on a unit that does not have the arm motion and you do your own natural arm motion, you not only do more work but you receive balance and core training as well. Be ready to hold onto the hand rails (try not to lean on them) should you need them to catch your balance or rest.

Recumbent Bike- This bike places the rider in a reclined position. For most enthusiasts the advantage is ergonomic; the rider’s weight is comfortably distributed over several square feet of the back and buttocks. On a conventional stationary bike, the body weight rests on a few square inches of the sit bones and the hands. Recumbent bikes provide added comfort for bike lovers with the added back support from the seat. Comfort is not synonymous with easy in this case. You choose your intensity level. Because the legs are more level with the torso, the venous return back to the heart is very efficient. The lower body workout from both types of stationary bikes is excellent.

Stationary Bike- Upright bikes take up very little space. Bikes provide both fun and fitness to many walks of life over the years. They are a non-weight bearing form of CV exercise. This does not mean the workout will lack intensity; quite the opposite is true.

Stroke Volume- TThis is the volume of blood pumped by the right/left ventricle of the heart in one contraction.

Treadmills- Treadmills provide an excellent weight-bearing workout. Walking and running are natural motions for us as human beings in locomotion. Treadmills provide a smooth and very predictable terrain, meaning no rocks, obstacles or uneven surfaces. Most on the market now provide flexible decks as well. Both of these factors add up to a safe and comfortable workout for the user.

Tread Climbers- This is a hybrid of a treadmill and a stair climber, hence the name. Tread climbers have two separate revolving belts that you walk on which also move up and down in a stepping motion. So you are essentially combining the two machines which looks and feels much like you are climbing stairs.

Versa Climbers- This combines both lower and upper body exercise into a vertical climbing motion.
