Stairmaster PT4600HR Free climber (Purple Face)

The latest evolution of state-of-the-art climbing machines, the 4600PT FreeClimber delivers a vigorous cardio workout in the comfort of your own home. The 4600PT is outfitted with an electronically controlled alternator with a chain drive that precisely controls the pedal descent, letting a wide range of users find the perfect workout pace for their fitness level. The patented independent pedal geometry, meanwhile, keeps the pedals level throughout, ensuring a biomechanically correct movement that won't strain your muscles over the long term. And thanks to the cushioned, one-piece foot pedals, the side handrails, and the easy-grip upper-body handles, almost anyone can find a comfortable stepping position.

The 4600PT offers a step range of 1 to 14 inches and a step rate of 26 to 174 steps per minute, depending on whether you want to step hard or maintain an easy pace. Also along for the ride is an easy-to-read, custom LCD display that offers six workout programs with integrated progress monitors: quick start, manual, fat burner, calorie burner, speed intervals, and heart rate zone trainer. 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.
