StairMaster has launched its new StepMill 3 (SM3), the fitness manufacturer's most compact stair climber.

With pre-programmed and customisable workouts, heart rate monitoring, workout feedback and more, the streamlined, SM3 is designed to help users achieve a highly effective cardio and strength-training workout in a home or office setting.

By replicating a real stair climbing motion, the SM3 delivers a challenging, functional workout that targets the quadriceps, hamstrings, glutes, calves, and core.
