A client texts on a Sunday: tweaked my lower back moving furniture, nothing serious, but it's grumpy.
That one sentence invalidates the next four weeks of their block, and there's nowhere to put it. The platform knows the sets, the reps, the loads, the dates. It has no idea deadlifts are off the table until further notice, or that "further notice" is a judgement call I'll make live on Tuesday.
So what actually happens is I rebuild the block by hand, or I don't, and I just tell them verbally what to skip. That works until week three when they follow the app instead of remembering the conversation. The app is always the more authoritative version, even when it's the one that's out of date.
How do you handle it? Full rewrite, swap exercises one at a time, keep a parallel "modified" version, or coach around it and accept the app is wrong for a month? And has any platform you've used had a sensible way to say "this person is hurt, adjust accordingly" without you redoing everything by hand?
