Sturdy and Intelligent Shock Absorbing Deck

Take it easy on your knees, back, and joints with the TR4000i that features a sturdy 1” deck and 8 compression shocks that reduce noise and absorb foot strike. The 22” x 60” running surface and robotically welded, all-steel frame are engineered to simulate real-world conditions and withstand miles of use. The TR4000i is designed with intelligent features to help you reach your fitness goals faster. The patented Intelli-Guard system ensures your safety by automatically pausing the belt 20 seconds after you step off, so you can step back on with ease. And the Intelli-step feature works like a built-in pedometer to automatically count your steps, so all you have to focus on is how far you can push yourself in your walk or run.

Buying a Treadmill

Fitness Town has curated a range of quality treadmills that pass our expert team’s test. After decades in the fitness industry, we have a good understanding of your needs, no matter your age or level of fitness. We consider popular preferences, diverse physical stature, and training requirements from low to high intensity. You can rest assured that products at Fitness Town have passed our test and we are a match for you. Now we just need to fit you and your environment with the treadmill that moves you.

Here are some things to consider when comparing treadmills:

  • Your stride length: If you are tall, you’ll need a treadmill with a long enough deck to accommodate your stride. Remember that your stride is longer when run. If you’re over 6′, we recommend trying a treadmill at one of our stores.
  • Your weight: Manufacturers post maximum weight limits. If equipment longevity is important to you and you are at the top end of the weight limit, you might want to consider a treadmill with a higher weight limit. This is because higher weight (especially exercising at higher intensity) will cause greater wear and tear on the treadmill. Regular maintenance will help but it’s important to get the right treadmill for your size.
  • Your training goals: If you plan to walk 30 min a day a few times a week, you can get away with a value priced (lower cost) treadmill. If you plan to run at high intensity for an hour a day, you will enjoy your treadmill experience and your treadmill will last longer if you look for a higher-end commercial-grade treadmill.
  • Number of people and frequency of use: The number of people in your household using the treadmill impacts the frequency of use and, therefore, the wear and tear on the treadmill. We carry mid-to-high end treadmills
  • Do you cohabitate? If you live above someone or will you be using the treadmill in close quarters? Consider the noise level of the treadmill. The motor, suspension, and a good under-treadmill matt are variables that impact noise.
  • Your environment: If space is limited, consider one of our folding options with wheels that make tucking your treadmill away easy. But, remember, it’s not the 80s anymore; we don’t have to hide equipment in the basement and bedroom anymore. Fitness equipment design has come a long way and having your treadmill in a common area will not only increase the likelihood that you’ll use it; it’s a bit of a lifestyle statement you can be proud of.
  • Cool Features: Notice we list this last. That’s because the considerations above will help you narrow down your most important requirements. These days, even entry level treadmills come with some pretty swank features like connectivity, sleek consoles, and more. IMPORTANT: Don’t be swayed to buy a treadmill just because of a cool Connected Fitness App that lets you run with friends or with an instructor. You can use those apps with ANY treadmill so get the right treadmill at the right quality and price for you.
