I've had a "free" yard sale exercise bike in my covered lanai for about 2 years. It has electronics. Since I have nothing invested in it, I wasn't too concerned about how it would weather. In a heavy, windy storm, water can blow in there and get it wet. The electronics seem to be well protected and they still work. There is a little rust on some of the metal parts.

So, if you have nice equipment that you want to keep nice and working, an open/screen lanai is probably not a great solution. I have seen some folks keep exercise equipment in their garage.
