Knowing my love for exercise and high-tech innovations, Forbes.com interviewed me for their latest review of state-of-the-art fitness equipment.

The machines they reviewed range from the relatively inexpensive Bowflex SelectTech 552 Dumbbell set ($399) to the pricey cross-training ROM Time Machine ($14,615), part and parcel of a sporting goods industry that hit the $5 billion mark in sales just two years ago.

My advice for the best equipment to buy or use: An elliptical machine that trains all your leg muscles with less force on your joints than walking. Even better is an elliptical that allows you to change the incline, so you can get a complete workout.

One of the coolest machines spotlighted was the Precor EFX 5.23 Elliptical with a patented feature that exercises different muscle groups every time the incline of the ramp is adjusted.

If you've made the commitment to exercise, a good place to start is my exercise resource page that comes with a free exercise table you can use to keep track of your progress.
