Improving stamina with fitness equipment
Building your endurance on a bike
Opt for an exercise bike and look for a machine that continues to pose a challenge, even when your endurance has already improved. Train the strength of your leg muscles so you burn more calories, even when you're resting.
Building your endurance while walking
When you run on a treadmill or elliptical, you can build your endurance indoors. Treadmills with a steep incline help you quickly burn calories, while powerful ellipticals make it possible to train without heavily straining your joints.
