Two training modes.
The core use case is walking backwards against the brake resistance. Good for knee rehab and ATG-style training.
Weight the treadmill base down with plates and it turns into a sled push. More resistance, more effort.
It takes ~15 minutes. You'll need to drill three small holes into the treadmill base. Follow the link to a step-by-step guide with photos.
"It arrived when expected and it was easy to install. I had tried the doorstop approach, but I was stronger than the doorstops. This unit has solved that problem. Thank you."
"I was to make the same thing but with cnc'ed metal parts. Take my designed to a local machine shop and have them make it. But this showed up in my search and viola I just have to have it. Plus the cost of CNC service is unbelievable and not cost effective for a one off. Excellent idea and works 100%."
"Really well made. It looks like and works like it was designed to be a part of the treadmill. I bought two for aesthetic reasons but, like other reviewers have said, one is more than enough."
"Fits perfectly on the treadmill and offers a high or low amount of resistance. I can’t imagine needing 2 of these because I can increase the resistance to the point where I can’t move it. The instructions didn’t have pictures but once you see how it fits on the treadmill it becomes pretty self-explanatory. I’ve used this for a few weeks for ATG backwards walking and it’s exactly what I wanted. Thanks again!"
"Great fit. Easy to install. Can't wait to get to backwards walking on this thing. Ordering with hardware is definitely the move!"
"Great item. Does what it's supposed to do. Great communication from the owner. I bought my own hardware from Home Depot so it turned out to be a few bucks more doing that. So I'd recommend just getting the hardware added in when you order. Saves time and money"
This add-on only fits the Sunny Health manual treadmill. If you don't have one, here's a link.
