South Denver Cardiology Weighs In: The Pros and Cons of Running on that Treadmill

Many of us want to be a little fitter. Whether in the pursuit of a slimmer physique, a more active lifestyle, or a healthier future, exercise is a great way to improve yourself and your health! However, exercise can be time-consuming and difficult, so you want to be sure that you’re getting the most out of your workout. Running is one of the most straightforward yet physically intense forms of exercise, and is possible even in snowy weather thanks to treadmills. Many people turn to indoor treadmill running to keep off the pounds during the cozy winter months. But is this the best way to exercise? South Denver Cardiology weighs in on the pros and cons of running on that treadmill.


  • Convenience, convenience, convenience! Whether in your home gym or at a fitness center, treadmills make it possible to run no matter what the weather, morning, noon, or night.
  • Control and personalization: when running on a treadmill, you know exactly how fast and far you are going. You can turn the intensity, speed, and often even slope up or down to get the exact workout that you want.
  • Treadmill running can help you achieve your weight loss goals: consistent exercise on the treadmill burns calories efficiently, and with proper diet, treadmill running can lead to significant weight loss.
  • All of the muscular and cardiovascular benefits of running can be achieved on the treadmill! In particular, your heart, lungs, and leg muscles can become much stronger from regular treadmill workouts.


  • Nothing beats the outdoors: the smell of the trees, the rush of the wind, the scenery as you whizz by! Treadmill running just can’t top the feeling of running outside.
  • Expense: treadmills and gym members, while worthy investments, can be expensive. Running outside may have tougher weather conditions, but it’s free.
  • Joint problems can occur from running on the treadmill (as well as outside). While good form and proper gear, especially quality, supportive running shoes, can help to alleviate joint paint and damage, running is still a high-impact sport that can take a toll, especially on your knees and ankles.


South Denver Cardiology’s final verdict? Running, whether indoors on a treadmill or outside in nature, can be a great way to exercise and improve your cardiovascular health. Running indoors can provide a greater degree of control, but running outside can be more exciting and enjoyable. Remember, though, no matter where you’re running to watch out for knee and ankle pain and make sure to take care of your joints.
