The 2021 Treadmill Purchasing Guide by Sunny Health & Fitness

Congrats! You’ve decided your next piece of home gym equipment is a treadmill. But with so many options to choose from, and only so much space for a home gym, which treadmill is right for you and your home?

Below you will find detailed information on some of the top-rated treadmills for 2021 by Sunny Health and Fitness. This will make your treadmill purchasing decision easier.


Is A Manual Or Motorized Treadmill Right For You?

There are many types of treadmills out there available, but the most important decision you’ll need to make is if a manual or motorized treadmill is right for you. Keep reading to find out the difference between these popular types of treadmills.


Manual Treadmill

If you believe that the only person that can push you to workout is yourself, you’ll probably love a manual treadmill. Manual treadmills are a great cardio choice if you are looking for high intensity fitness equipment.

Manual treadmills work by having a running belt that engages with an internal flywheel mechanism. When you walk and push your leg back, that power is transferred from the running belt to the flywheel.

The faster you move, the more momentum you give the flywheel, and the more speed you can maintain. However, the moment you slow your pace, the flywheel slows down, and you will need to increase your effort to get it going again.

Some manual treadmills also have a resistance mechanism that can help you switch up your workout. This will make it more challenging to generate speed, but you’ll be able to burn more calories and condition your lower body even further. This applied resistance can also help you perform exercises like sled pushes with the support of multi-grip handrails.

However, just because these treadmills have manual controls doesn’t mean they lack incline. Some manual treadmills have various incline levels that you can adjust after you safely dismount the machine.

Combined with magnetic resistance, this can elevate your workout challenge, so you can burn even more calories. While manual treadmills can be used for challenging workouts, they also make great exercise machines for light cardio exercise.


Motorized Treadmill

Motorized treadmills can do the same things as manual treadmills (and more), but they serve a different purpose. While a manual treadmill is good for building endurance for short, high-intensity workouts, a motorized treadmill is ideal if you are a runner aiming for distance.

Simply put, you don’t have to make a conscious effort to keep your speed over a long distance with a motorized treadmill. Motorized treadmills tend to be heavier than their manual counterparts, but they’re also more feature packed.

You can track important variables like incline, heart rate, and calorie count. Other treadmills are equipped with auxiliary inputs, like hand pulse sensors for tracking heart rate, dynamic workout program buttons, and in some cases, loudspeakers for your favorite music.

These treadmills are also capable of performing HIIT workouts. However, motorized treadmills are often best suited for individuals that are looking for a tool to train for long distances. The motor can help runners maintain speed during long runs, encouraging them to keep up the pace.


Which One Should You Get?

Luckily, both types of treadmills can be beneficial to your workout routine. If you’re looking to start running, build endurance, and practice high intensity interval training (HIIT), a manual treadmill will work best for you.

However, if you find consistent speed, feature-packed setups, and long-distance running more appealing, then a motorized treadmill will certainly boost your workout regimen.
