Stationary cycling is one of the most effective low-impact aerobic exercises for increasing your metabolism for more efficient calorie and fat burning without the impact on your joints. The Stamina® Magnetic Upright 1300 Exercise Bike"s magnetic resistance gives you a quiet, smooth workout with a tension dial that lets you choose and change the intensity/resistance anytime during your workout. The large easy-to-read monitor with scan keeps you motivated during your workout by displaying speed, distance, time, and calories burned with one-button control. The oversized, cushioned seat is adjustable to fit most users for comfort and proper exercise form. Because it is an impact-free activity, stationary cycling can be a lifelong form of exercise. For effective aerobic exercise, work within your target heart rate zone (70% to 85% of your maximum heart rate).
