Elliptical Machines

The Skinny on Elliptical Machines
From Jillian Michaels

Elliptical trainers are great because they tend to have a lot of variables built in. Many have adjustable-incline ramps that allow you to work different muscles in your legs. Some also have movable handles that you can use to work your upper body. Obviously, if the machine you're using has the option for maximizing your session by working the upper body, use it.

When working out on an elliptical machine, it's important to increase resistance. Otherwise, gravity will be doing all the work for you. You can target different leg muscles by varying the ramp incline. If the ramp is inclined and you're pedaling forward, you're working the back leg muscles: the hamstrings, glutes, and calves. If the ramp is at a lower incline and you pedal backward, you're training the front leg muscles: the quads and dorsiflexors.

Elliptical workouts are really good for everyone, especially people with knee problems — they will find the elliptical machine to be a great cardio alternative to running because it is much easier on the joints.

Hop to It
What form of cardio can you do anywhere? No matter where you are or what the weather, you can always jump. It will take a little time to build up endurance for this form of cardio, so try it in intervals at first: Jump one minute, rest the next, and so on. Jumping is an outstanding form of cardio, both for burning calories and toning your quads, hamstrings, and calves. You can jump up and down, jump rope, do jumping jacks, or get creative — the possibilities are endless.
