I know a lot of people think this is going to help them exercise at work, but that isn't what I bought my Cubii Pro for. I've had CFS/Fibro for 25 years. I was simply looking for something I could do while I was sitting to get the circulation flowing throughout my body. I bought the Pro version so I could use an app that syncs with my FitBit.I have two very bad knees and sitting on the couch exercising with this machine hasn't bothered them AT ALL. The first time I used it I was surprised that I really felt it in my inner thighs, but luckily they didn't hurt the next day. Unfortunately, I had to stop using it after the first time as I'm exhibiting symptoms of COVID-19 and using the machine even for 15 minutes made my temperature go up more than I cared for it to. I thought getting some exercise would help my body fight the virus, but I guess not. I look forward to using my Cubii Pro as soon as I get that issue straightened out because it's VERY easy to use and as anyone with Fibro knows there is little you can do that doesn't automatically set off your trigger points! In that regard, this seems like the perfect machine to use, at least for me.I love the app - it shows real time exercise - how many cycles, calories burned, etc. as you're doing the exercise. This helps you figure out what resistance you need to use to get the calories you want to burn as you're doing it. When you're done, you simply click the sync button and the exercise is immediately entered into your FitBit dashboard.The machine itself was very easy to set up. You screw in 4 screws that attach the footpads to the base and you're done. Word of caution though, don't expect your grandma to be able to put this together by herself. This is a serious piece of exercise equipment and seems built to last so it's heavy. Now heavy is a relative term. As a 60 year old who has had CFS/Fibro as long as I have and can't take pharmaceutical medications for it my only pain prevention was to move as little as possible. This machine weighs from 25 to 30 pounds so getting it out of the box and moving it around to assemble took some effort. While it has a wonderful, well placed handle to move the item around while you're not using it, if you misstep and the metal part of the machine hits you, it's going to leave a nasty bruise. I use a crutch so my mobility isn't the best. I have to be careful to make sure I'm in a secure position before I move the machine. It's roughly 23 inches front to back and 18 inches side to side and while the handle is perfectly placed, it's still going to be heavy for some people to lift.I saw a lot of reviews that said people bought this as what they thought was an opportunity to do some type of cardio while they were at their desk. This is not at all what I bought it for. I bought it because I'm an older person who needs to keep her circulation flowing, a problem a lot of people have as they get older and less mobile. I'd recommend it for any older person to use for that purpose. Buy it for your aging parents who don't move around a lot, put it somewhere out of the way that they can reach if they swivel their chair around (so they don't have to move the machine itself) and let them go to town. It's very easy on the body and perfect to use if they sit around watching TV all day. It's also good for anyone who sits at the computer all night gaming with a group online. That way you don't have to stop what everyone is doing to get up and walk around.For me, the sturdy build of the machine, the bluetooth connection and the app made it worth the price of the machine, especially for someone with few exercise options. If you love your parents and want to keep them around and they don't seem terribly mobile, this might be a really good option for them as they can do it while they're sitting. As always, consult with their physicians first and make sure you set it up so they can access it without having to move it around (and it's not anywhere they can trip over it). It's definitely worth the effort.
