Hate it so much… it’s great!!

I developed a lot of muscle atrophy after I dislocated both knees, developed arthritis n both knees also. I hate feeling that I missed a step but since I got this treadmill my life has benefitted from it. My endurance has increased, I’ve lost weight, I feel different and look more fit (well more fit than I was). I also developed lower back problems from my bad knees and this treadmill has actually strengthened my core. I do heavy PT at home every other day but this manual treadmill kicks my butt. At first it was difficult but eventually you get a feel for it but you have to try. I started a walking mile of 25 min to an excellent light mile run of 13:45 mins. It wipes me out and gives me a heavy sweat but it is totally worth it, the bounce back of the deck allows me to lightly run whereas I cannot do that in the real. Being on a cane and not being able to run in real was a bummer for me but this treadmill is completely worth it. My roommate saw the progress I was doing and they decided to hop on also, they are still getting use to the treadmill but they say that they are seeing results. Gave me hope of being as close to my norm that I use to be. Love it!

Great machine -- on it right now writing this!

I've been religiously working out to a daily routine since 2008, been through half a dozen machines, three treadmills, never a curved treadmill! This thing is making me sweat and breath harder than any typical motor run treadmill. I just wanna quit after 30 minutes (but I don't) because it's making me work, and that's how I know its awesome! On top of that its smooth and solid! Recommend it to anyone who knows a hard workout is the best workout. SB Fitness customer service (Brant) response is also amazing! This is a solid Penn. (Made in USA) business I'm proud to have purchased from!

CT400

Very happy with the treadmill. Shipping was prompt and arrived in great condition. The FEDEX driver unloaded the box, removed the pallet, brought the box to my condo on the 4th floor, and took the pallet when he left. Assembly was not hard; did it by myself and took about an hour. I have used the treadmill every day since arrival and quickly adjusted to the manual treadmill. I did have some issues adjusting the belt after a few weeks of usage but Brant answered my questions promptly and everything is good. A good purchase.
