Unlock your full potential

No boring, mindless workouts here. No subconsciously going-through-the-motions-just-to-check-off-your-cardio-workout for the day. No online coaching or digital trails, attempting to trick your mind into believing that you're somewhere else. Nope. It's you vs. machine now. It'll take every conceivable effort you can give, both mentally and physically, if you want to go toe to toe with this treadmill. And with 8 levels of resistance, it is going to tax you in every way you can imagine and even in ways you cannot. The only limitations this treadmill has are yours. If you want to get faster, stronger, and in the best shape of your life, you'll need a machine that will constantly adapt to your very best and will be able to push you no matter how good you are or how much better you become. And with full commercial construction, there's no worry of wearing it out. The CT700 can't quite say the same for you though.

Get a more efficient workout in a fraction of the time

Both scientific and anecdotal evidence agree, a manual treadmill will give you a better workout in less time than a motorized treadmill. There's a reason that running on a motorized treadmill is so much easier than running outside, and it's not just wind resistance and uneven ground. When you run outside, you activate your quadriceps, hamstrings, gluteals and calf muscles to propel your body forward. A curved treadmill activates the same muscle groups, giving you a complete running experience In the comfort of your own home. Plus, the natural curve offers a much more bio-mechanically sound running form without all the impact on your ankles, knees and hip joints. Not only are you the driving force behind the movement, but the amount of calories burned are increased exponentially compared to a motorized treadmill as it increases your work and your energy output at a higher rate, giving you a better work out in a shorter amount of time.

CT700 Curved Treadmill

Delivery was great and set up was easy. I’ve been walking on treadmill for years, just went an hour on this and I can feel all new muscles in legs, glute and core. The time flew by, not boring like a treadmill. The CT700 is a beast and a great product for half the price of most others I demo’s. Customer service/ support answered me on a Saturday while setting it up. I would 100% recommend this product to all and anyone thinking of switching from a traditional powered treadmill.


This is an excellent manual treadmill. I do recommend you have a place picked out with plenty of room for the rails as they are a very large nice set of handrails. Comfortable to walk or run on,very easy to install the rails when it’s delivered. Make sure you have them put it as close to where you’re going to move it into, took an extra large dolly for us to move it from the garage into the home. I have had it over a month now and so far I truly do like it better than electronic one.

Nothing but quality

The thing is a tank. High quality steel bearings that are super smooth. Could even run barefoot/minimalist shoes if you wanted, more comfortable than a regular flat treadmill. I hit 18mph sprinting on it and it wasn't shaking even a bit, it's solid.
Build instructions were easy to follow, I recommend but tightening everything until the end, some metal bars take a bit of aligning to get right and it helps to put the bolts in but not tightening so you can move the arms/ handles around.
I had a bolt missing on my unit, I reached out to Chad in the morning and by the afternoon he sent me a tracking number for the part, amazing customer service. Treadmill was shipped in a very sturdy crate and delivered to my garage. Overall 5 star experience.


As advertised. High quality components. Very sturdy piece of equipment. Customer service was great

Amazing treadmill / customer service

I reviewed many curve treadmills over several weeks before purchasing, and decided on SB Fitness’ CT700. However, I was disappointed SB Fitness did not ship to Hawai’i. I contacted Brandt at SB Fitness to express my desire to purchase a CT700, surprisingly he was willing to ship one to me after an agreement to share the shipping cost. I was in receipt of my CT700 in four (4) weeks securely packaged in a sturdy wooden crate. With the help of my wife, we unpacked / put it together in a couple of hours, shortly thereafter, I did my first run . . . it was everything I had expected!

My entire experience with SB Fitness was “Customer Service,” at its highest level, and like my CT700, it’s nothing short of five (5) stars! Mahalo Nui Loa!!
