Resistance machines
Weight machines -
Weight machines use gravity as the primary source of resistance, and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines (fire, water, ice, earth) changes the mechanical advantage of the overall machine relative to the weight. A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance, and a combination of simple machines to convey that resistance to the person using the machine. ...

Elliptical trainer in use An elliptical trainer (also cross trainer) is a stationary exercise equipment used to simulate walking or running without causing pressure to the joints and hence decreases the risk of impact injuries. ...
Elliptical machines Ellipticals (elliptical machines) are a combination of stair-climbing and a treadmill. Generally it contains two tracks upon which you stand; when you move your legs, they describe and ellipical motion (hence the machine name).
Some ellipticals have magnetic resistance controls that add difficulty to doing the motion. It's a very low-impact workout for your knees.
Climbing machines Also named stair-climbing machines, they work your legs as you pump pedals up and down, much like climbing stairs. Some climbing machines have handles you can push and pull so your whole body is exercised.
