If you've ever been hiking, you know that it works your entire body - all your muscles, joints and most importantly, your heart. You can hike up a mountain in the winter, but most people choose not to because it's so darn cold and windy.

Recently at the gym, I saw a new machine and just HAD to try it. It's called the Summit Trainer.

I guess it could be compared to a StairMaster or an Arc Trainer. But it's more like hiking than anything else.

You move your feet like you're stepping or climbing up a hill and you can either keep your hands on the front handles, or for more intensity, you can move the side "arms" as well for a total body workout. It also has a built-in digital heart rate monitor located conveniently on the handles.

You can choose a workout that will automatically adjust the resistance level to keep you in your target heart rate zone. Or you can do interval training workouts. You can also set personal goals and the Summit Trainer will give you a workout to meet them.

Not only is it great for your heart and muscles, but it'll get you ready for warmer weather when you can do the real hike thing.
