I'm interested in learning more about the different types of exercise machines.

The most common type of exercise machine is a stationary bike. It allows you to pedal and move your legs while you remain stationary. Another popular type of exercise machine is a treadmill, which simulates running or walking on a flat surface. Strength training machines are designed for resistance exercises such as lifting weights or pushing against a bar. Elliptical trainers use an elliptical motion to simulate running and cycling. Finally, there are also rowing machines that allow you to pull yourself along with cables attached to a handlebar.
