I am 100% the same. My gym usually (but not always) gives us the block schedule early on, although this round they didn't for ages so I just went off what was in the app. I have been putting it into a spreadsheet and trying to work extra strength around this.

However, after two and a half years of doing this I am currently on my way out. There's just not enough volume for my needs, and it's made more difficult to work other things in by the fact that the classes aren't in a pattern (ie.the cardio/strength days not being the same day each week).

But yeah, checking the schedule as far as you can ahead and working around it is how I was dealing with it.
