Also commonly known as a stair climber or step mill.
This piece of exercise equipment is designed to simulate the action of climbing stairs, providing a cardiovascular workout that primarily targets the lower body muscles, including the glutes, quadriceps, hamstrings, and calves. It features a continuous loop of revolving stairs or steps, handrails for support, and a console that displays workout metrics such as time, steps climbed, and calories burned. Stair trainers are used in gyms and homes to improve cardiovascular fitness, build lower body strength, and burn calories.
