A treadmill primarily engages the lower body’s major muscle groups. These include the quadriceps, hamstrings, glutes, and calves. Walking or running on an inclined surface further activates these muscles and can also engage core muscles for stability. For instance, increasing the incline engages the hip flexors and reinforces postural muscles.
Developing strength and endurance in these muscles contributes to improved cardiovascular health, increased metabolic rate, and enhanced physical function. From its origins as a tool for labor or punishment, the treadmill has evolved into a ubiquitous piece of exercise equipment, facilitating physical fitness and rehabilitation. Its ability to provide a controlled and measurable workout makes it a valuable asset for individuals of varying fitness levels.
