This winter there haven't been many good walking days, so I'm forced to improvise. I have a stationary bike, but after sitting all day for work, more sitting on a bike doesn't really feel right. I do have exercise DVDs and I'm fortunate enough to live in a two-story house, so I can do stairs. A loop through the house, down and up the basement stairs, another loop, then down and up the stairs to the second floor and another loop around the upstairs, all multiplied by however many times I want to do the circuit works, but it's not something I do every day.
To mix things up now and then, there's...YouTube. A quick search turns up a number of Virtual Walks, videos where someone took a video of a walk along an interesting path, which enables a person (me?) to pretend to also be traversing that path as I walk in place (or a little forward and back/side to side/whatever works to keep me moving). There are also Virtual Jogs, the same thing except at a faster pace (do a search for Virtual Run or Virtual Running and you'll come up with a few more).
I also did a search for Walking Videos (ones with an instructor/leader), but I didn't post the results for that, because a lot of what came up were Leslie Sansone's videos, and I know that she sells those, so...someone probably filched them. But there are others available on YouTube. Jessica Smith has an entire channel, and a search of her videos narrowed it down to her Walking Videos (but do search the rest of the channel, since she has other types of workouts, and they're all done in a small space, for those of us who don't have a lot of exercise room). Here's one:
Another possibility is the LiveStrongWoman channel. Some of these are very intense, but a search of the channel for Beginner turned up a number of videos (mostly Yoga and Pilates) and another search for Intermediate turned up more. Here's a beginner yoga video:
There are also other fitness channels: Lionsgate Befit, Tiffany Rothe Workouts, Fitness Blender and BeFitin90. There's also HASfit, which has a broad range of workouts for all experience levels, including exercises for seniors, such as this one (the audio quality isn't great and I think that it would have been better without the music, but...it's free, so...):
That's just a small sample of the exercise channels, so I'm sure you can find more. Other things to search for might be Dance Exercise, Dance Lessons or specific types of exercise, dance or dance exercise. Examples might be:
Strength Training or Weight Training
(And I'm sure there are many others I haven't thought of)
Obviously, you don't want to do any of these things unless you are fit and have the all-clear from your doctor, so do make sure your physical condition is such that the exercises will not be harmful to you.
In conclusion...wow! This was a long post. I hope you found something here of value. Have fun!
