Stairclimbers are available in two types, based on the stepping motion. Independent stairclimbers have pedals that respond specifically to the exercisers' pressure. When an exerciser stands on the pedals, they both sink to the ground until the user begins climbing. The newest category in cardiovascular equipment is the elliptical machine, or cross-trainer. Seen as a combination of a stairclimber and a cross-country ski machine, this type of equipment features pedals that follow an elliptical pattern and can go forward or in reverse.
Some models also have an optional incline for the pedals.
Others feature upper-body exercise as well by including arms that move in synchronization with the foot pedals. Cross-training machines have surged in popularity because they are easy to use and have minimal impact on the joints. Although exercisers may be working vigorously on a cross-trainer, they perceive less exertion than when performing a comparable exercise at the same intensity such as running. The choices of strength training equipment are even greater than with cardio equipment. As with cardiovascular equipment, a reputable fitness equipment dealer can offer useful guidance.
