Change it up
Likes: Exhilarating, effective and addictive. I loved the variety and challenge; it can be a different workout every day -- or every minute. Allowing you to move the way you want, from easy to all out, it encourages a harder workout than a normal elliptical. The stride length automatically varies from zero to 27 inches, as you step, stride, run, walk or anything in between. Includes resistance adjustment, heart-rate programs and a variety of workout programs but no elevation controls, only a lighted "interactive stride length" dial that lets you watch and experiment with your own real-time motion. Relatively floor-space-friendly at 56 inches long.
Dislikes: As a commercial-grade machine, it's priced like a used SUV.
Price: $7,995. (425) 486-9292; precor.com.
Octane xRide: The world's first seated elliptical machine.
Likes: Although originally intended for older people, it provides a superb workout for all ages. The comfortable seating position calls to mind a new and improved recumbent bike, with the short seat and back pad gliding up and back at a 45-degree angle. The back pad also tilts for a custom fit. Great variety; programs allow all-body, arms-only and legs-only workouts. Multi-position handlebar lets you work arms at different angles.
Dislikes: Poor control-panel placement. Although I'm of average height (just over 5-foot-9) I had to reach forward, off the back pad, to press the resistance and workout keys. While merely irritating for me, it would be harder to manage for short, senior exercisers. A land yacht at 71 inches.
Price: $3,799; xRide6 (with no heart-rate monitor) is $3,199. (847) 638-1582; www.octanefitness.com.
Almost like running
Vision S7200 HRT: Suspension elliptical trainer.
Likes: Super-smooth, solid feel even when you're going all out. The stride length automatically lengthens from 20 to 23 inches as you speed up or increase the incline, so you can simulate a hands-free, near-running motion. It has a natural elliptical footpath, with footpads that have less of a forward and backward tilt than other brands. Includes narrow-spaced (and therefore natural) foot placement, a variety of heart-rate programs and the highly challenging and effective Sprint 8 anaerobic interval program. Just 57 inches long.
Dislikes: Poor panel-control placement. When pressing "up" and "down" keys, I had to thread my fingers carefully through obstacles such as the heart-rate grip bars and a water bottle.
Price: $3,799. (800) 335-4348; www.visionfitness.com.
PaceMaster Silver XT: Conventional-looking elliptical with an unconventional feel and programming at a price that's a relative bargain.
Likes: Great deal. As rock solid and smooth at full speed as a $5,000 machine. The company attributes that to a double-strut drive system that separates the footpads from the motor-drive system. Very good pedigree -- this is the first exercise machine that is not a treadmill from PaceMaster, a highly regarded manufacturer known for high quality at a moderate price. Twelve programs include a unique heart-rate-control mode that adjusts resistance to keep you in the same heart-rate zone. Includes double water-bottle holders and a handy, nonslip iPod tray.
Dislikes: Does not offer elevation change. Eats up lots of real estate at 79 inches long.
Price: $2,199. (973) 276-9700; www.pacemaster.com.
