Instead of spending money on expensive equipment you might not use, why not buy something used? There are always treadmills, etc for sale in my area and I, actually, got my treadmill at a place that sells used exercise equipment... might have been "Play it Again Sports" or something like that. I'm glad I didn't spend the money to buy a new treadmill because for a lot of the time I've had it, it's been a blanket rack... I do have it set up now in the room I'm using for an art room. I have it facing the window so I can see outside while I'm on it, listening to my tunes. Not like walking outside, but better than staring at a blank wall. Unfortunately, I'm still not using it every day, as I should be.
Sarah had some excellent ideas. In addition, for other exercise, without a bike or treadmill, have you ever checked out Leslie Sansone? She has a bunch of walking videos and perhaps by now she might have a "community" you could get into for motivation and/or support.
Your Apple watch might have a "community" you can join as well. I have a Fitbit and they have a community to help each other stay motivated, etc, so I'm sure Apple does too. You might even find people in your own area that you could exercise with. I didn't join Fitbit's community, but I've thought about it...
There are a lot of YouTube videos of bike classes (or treadmill classes) if you need a coach and something to follow, and a ton of different YouTube channels so if you don't like one channel, you can try another. I believe some of these are live and you can chat with others in the class, some you may have to subscribe or pay for, but there are a lot out there. If you are looking for just general exercise classes, there are tons of yoga, weight/strength training, cardio, etc. classes on YouTube as well, some may have live classes where you can interact with classmates or the teacher. My sister loves FitnessBlender videos, just following the trainers on YouTube (not live) - FitnessBlender seems to be mostly cardio, bodyweight, and some weight training as far as I can tell.
There are also many Peloton competitors, with similar quality exercise bikes (or treadmills) at a reduced price, and many of these come with a year of classes for free, very similar classes to Peloton or SoulCycle, and there are lots of websites out there reviewing them.
There is also the Peloton digital app if you already own a (non-Peloton) exercise bike, and that gives you the same live class experience, for $20 a month.
My own thoughts about Peloton... if having a very expensive piece of equipment and paying $40 a month in perpetuity is what it takes to get you to exercise, and you have the money to spend, the space to put it, and the people who make financial decisions with you support it, then maybe it is worth it for you. That price tag might not be too high if you are used to paying $34 for one SoulCycle class, but it is way out of my price range.
Unless I really, really loved indoor bike classes - I'm not sure I would enjoy years and years of indoor cycling as my exercise of choice (again, I am a runner, so maybe I am already very biased - I do like the exercise bike at the gym occasionally, if I ever find myself in the gym, I will do the elliptical, bike, and rower before doing some weight machines).
One other thought -- many cyclists use Zwift when cycling indoors. It kind of makes biking into a video game, with an interactive map, other people biking at the same time and place with you. Not exactly the same thing as a Peloton class, but it can be fun. As far as I can tell, I think it is pretty cheap (or free?) to use. Runners can use it on a treadmill but need to get a device attached to their shoe, so there might be a low startup cost for bikes as well, and you need a bike you can ride indoors, many cyclists use a road bike mounted on something that lets them pedal indoors - I'm not sure how this works, but that is a much, much cheaper option than buying an indoor exercise bike.
And a second other thought -- if you have a way of tracking your activities (like a GPS watch or Apple Watch), there is an app called Strava which lets you share your activities with the Strava community or specific people who are following you. Kind of like Facebook, but just for posting your runs or bikes. (You can share all kinds of exercise, but the majority of users are bikers and runners). I've been running for decades, but started using it as a site to record my runs about 18 months ago (in addition to my GPS watch site). I've recently got my mom to post her walks that she records on her Apple Watch on Strava now, so we give eachother Kudos and cheer eachother on. It is one way to kind of have a "walking buddy" even if you are not together, you can check in and motivate friends and family.
If I had an instructor or even a virtual instructor that sang out "Good job! Go, Annie!" to me, I'd find that motivational. That was why I gave up on the one I had, she was quiet when I did things and tried to be funny, but never smiled, and I just thought she was thinking she would rather be doing something else besides work this middle-aged lady through the weights.
This company wasn't actually doing all that well until covid. That really helped it because people needed to find a way to exercise. It only recently became a publicly traded company, and again, it wasn't doing all that well. One of the regular commentators on the business channel CNBC said in his house his wife uses it as a clothes hanger. My experience with home equipment is mixed. My wife bought both a stationary bike and an elliptical machine, and we did use them quite a lot for awhile. In fact we broke the elliptical. The new one was more like a standing bicycle, and both machines eventually just became sculptures in our basement. I also find the commercials for Peloton really funny. They always show someone ripped and toned sweating in their beautiful living room next to a big glass wall looking out onto a woodsy backyard that none of us are probably wealthy enough to have. Clearly these people didn't get their bodies riding a stationary bike, as that only works the thighs, really, and the heart. They got those muscles in the gym. I think we divide into two categories -- those who like group exercise and those who like the meditative quality of solitary exercise. I liked group exercise when I did kung fu, but I was also learning something sort of useful, but practice was very solitary. But the group classes at the gym seemed ridiculous to me. I guess if you like that sort of thing and don't want to risk the gym now, any app, and I'm guessing there are thousands of them, can make it seem like you're not alone. I would personally recommend that anyone who wants to ride a bike get a bike and go outside. Ride places that are fun to see. Ride bike trails, they're fun. When the weather is bad, then it's good to have home equipment, but seriously, what do you need to be told to ride a bike or run a treadmill? It's not complicated, like yoga or pilates or aerobics. It just sounds to me like a very expensive way to do something we all learned to do as kids. Peace.
We have had an exercise bike, hopefully placed right in the TV room so we would use it. Did we? No. We now own a very nice rowing machine. Someone has used it two or three times since the beginning of the year.
It seems like the value of Peloton would be only in if it is motivational. If someone is prompted by the high price to become a fanatic for exercise, more power to he and to the program. I've paid to become a gym member before (even hired a private trainer to work with me on the weights) and didn't find it motivational enough (despite the price) to go in between the appointments. (I also didn't like the trainer very much, found her approach kind of pushy and felt she thought I was a waste of time. I stopped using her services when I tore a muscle under her tutelage, but that was just an excuse to get out of the whole unhappy experience.)
So, if someone is the kind of person who is going to get the value out of something because it cost a lot of dang money, maybe there is a lot to be said for an expensive program. But if all it will do is make you sorry you spent the money, like me with my gym, then probably no program would do a lot of good.
