And serious workout enthusiasts will dig the nationally recognized fitness test, which gauges individual progress, and the custom firefighter fitness test (CPAT). Other details include 20 resistance levels, Polar-compatible wireless heart rate monitoring, a maximum weight capacity of 300 pounds, and such user amenities as a reading rack, water bottle holder, and accessory tray.

About StairMaster
In 1983, a Tulsa, Oklahoma company created a fitness training product line that stepped up exercise to a new level--StairMaster machines. The invention was credited for being "among the first machines to turn gyms into modern exercise arenas" by USA Today, the nation’s most popular daily newspaper. Along with PDAs, laptops, and mobile phones, StairMaster machines have been labeled among the top 25 inventions that changed our lives over the past 25 years (USA Today, May 21, 2007). In fact, it was the only fitness product on the list.

More than two decades later, StairMaster products are still hard at work in gyms and homes preparing everyone from elite athletes to people in uniform, while being mentioned almost daily in the nation’s news media and sitcoms like Seinfeld. Ed Viesturs, America’s leading high-altitude mountaineer, relies on StairMaster trainers to prepare for climbs such as Mount Everest. "I do an hour on a StairMaster with a 50-pound pack on my back after simulating climbing movements in the gym," said Viesturs in Outdoor magazine. "These sessions hurt, but not as much as having to walk away from a climb because you weren't fit enough."

American hero Jim Campbell also looks to StairMaster trainers to maintain his physical readiness. A firefighter from Indianapolis, Campbell set the StairMaster StepMill record in 2006 (113.4 vertical miles in 24 hours). More than just a hobby, Campbell put his intensive training to use by rescuing a person trapped on the second story of a burning building--a feat that earned him a special commendation. Campbell joins thousands of firefighters who routinely train on StairMaster products to maintain top form. Are StairMaster machines a good solution for safe and effective lower body and cardio conditioning? Just ask each new firefighter candidate who must achieve 60 steps per minute for 3 minutes on a StairMaster StepMill while wearing a 50-pound vest and fire protective clothing ("turnouts").

By Steve C. Lochow on November 5, 2008
I bougth a brand new 4600 CL online. It did not work from the day I got it and I have now had it about 1 month. It will not work over level 12 (It should go up to 20). At level 12 I can only get my heart rate to 130. I have been dealing with Nautilus/Stairmaster for a month now with no progress. They keep assuring me they will fix it (as it is clearly under warranty). I so wish I could send it back, but that's not easy to do with piece of equipment of this size/weight. So I am stuck with a $3400 piece of broken equipment. This is incredibly dissapointing as I debated on this expensive purchase for weeks.

The Stair Climber Was shipped to me broken. It slipped and wasn't refurbished as promised. Calling the company on a Saturday morning called me back in 15 minutes. They paid for a technician to Drive 2 hours 2 different times to fix the issues with the machine. They have earned my highest respect in belong a company standing behind their product. I would recommend this purchase to anyone.

Great product that is not easilty found in health clubs anymore. I find it is unmatched by its exercise potential with low impact and good aeorbic function. I can read and exercise at the same time.

I use a 4600 every other day for my cardio. (The other days I use a Precor elliptical.) The 4600 has an alignment issue for me - the handles are too far away. I find myself struggling to stand up straight on this thing after awhile. On the 4200 they had what looked like a wide-based paperclip-shaped handle that was closer to your body so it was easier to stay verticle, and focus on your motion.
The 4600 I use is in a gym at work and it gets a beating and has been reliable over several years. Nobody takes care of it.
But this issue makes me give it a middle-of-the-road rating. I don't know why they didn't pay attention to the alignment.
