Best treadmills: 2021's top treadmills for your home

The past year brought home-based fitness equipment like treadmills into the spotlight. Thankfully, some of the best treadmills of 2021 are ready to help you meet your at-home fitness goals.

The past year has disrupted many of our daily routines, including our exercise routines. Those early morning trips to the gym we used to love (and hate) were affected like everything else. For some, that hour on the treadmill before work went away and became eight hours of work at home with no morning sweat session to get the mind and body ready for the day.

Many people had to turn to gym alternatives during the quarantine. Purchases of at-home gym equipment surged during 2020 and are still on the rise. Some opted for a few dumbbells and a fitness ball, while others decided to go all out in creating the complete home gym equipment experience. One piece of home gym equipment that saw a rise in purchases was the treadmill. 

A treadmill is an investment, not only for our health but for our wallets. The price of treadmills can range from non-bank breakers to costly ones. They all boast different features: size, speed ranges, running surfaces, inclines, and smart-technology capabilities. It is best to find one in that sweet spot, one that meets your fitness goals, budget, and the overall needs of your household. 

The following treadmills have a little something for everyone.

What are the health benefits of treadmills?

Not everyone has the benefit of a treadmill desk waiting for them at work to help boost productivity. But having one to use at home can afford the same benefits. The treadmill remains a top choice for people opting for a piece of at-home gym equipment for its wide-ranging health benefits.

  • Cardiovascular health: A treadmill is a form of cardiovascular exercise. This type of exercise can contribute to overall heart health. 
  • Weight loss: Calories in and calories out is the name of the weight loss game. Treadmills can help burn calories more quickly than other types of aerobic exercise
  • Muscle tone: Treadmill exercise works out multiple muscle groups at the same time. It truly is a full-body workout as core muscle groups are constantly engaged.
