Which machine is commonly used for cardiovascular training in PRT?

The treadmill is widely recognized as a common machine for cardiovascular training in Army Physical Readiness Training (PRT). It effectively simulates running and walking, two fundamental exercises that align closely with the physical demands placed on soldiers during training and operational activities. Utilizing a treadmill allows individuals to adjust speed and incline levels, providing a customizable cardiovascular workout tailored to different fitness levels and goals.

Although other machines like the rowing machine, stationary bike, and elliptical trainer also contribute to cardiovascular conditioning, the treadmill's versatility and direct connection to running—a primary fitness requirement—make it a staple in PRT programs. This focus on running is crucial since improving aerobic capacity is essential for enhancing overall physical readiness, endurance, and performance in various military tasks.
