There's not much to treadmill workouts. In most cases, you choose a speed or a workout program and you're set. However, there's a perennial question that everyone asks: how do I reach my fitness goals without surrendering to endless boredom? Thankfully, the solution lies in an activity that many Americans already do: binge-watching. Thanks to Netflix and countless other streaming services, you can turn your TV time into treadmill time.

The Strategies

When you start a binge-watching workout, make sure you have plenty of water and snacks handy. Although workouts are excellent for burning unwanted fat, it can be unhealthy to lose weight too quickly. Furthermore, treadmill workouts do no good if you don't have any energy.

Start and end your walks with slower speeds, which help stretch your muscles, reduce aches and prevent injuries. If you plan to run at a fast pace, take some time to perform a few muscle stretches. Be sure to rest from your walks when you need to. Once you meet your weight loss goal, walking can help maintain your weight and strengthen your muscles. To work your upper body, small, handheld weights add more depth to your treadmill workout.

While it is possible to walk for hours on end, try to limit your workouts to an hour or less until you get used to the workouts  effects on your body. If you have any concerns about whether or not you should walk on the treadmill for long periods of time, check with your doctor. A slower pace or a different type of exercise equipment   an elliptical machine or exercise bike, for example   might be more appropriate if you have special medical needs.
