In reply to raussmf:
There are a few more things to consider...
1. There is a less obvious danger with finger-boarding at your level which is that when you get back out climbing you'll naturally rely on your new-found finger strength rather than good technique (which will be disappearing through lockdown). So, try to get inventive about things you can do at home to maintain some semblance of lower-body technique. For instance, I've always found high step-ups onto sloping holds really hard (obligatory for gritstone slabs) both in terms of flexibility and balance. That's the sort of thing you can easily simulate at home (a 'toe-board'). Think about your technique weaknesses and get inventive! Also, if you're gym-strong you are likely to get more 'static'. Think about how you can incorporate balancey & dynamic moves into your routine to help the muscle remember.
2. 'Core' means different thing to different people, but one aspect I would make sure is in your program is full-range-of-movement exercises of the shoulders and hips. If you're doing even careful finger-boarding and pullups, it very easy to end up with lazy shoulder/hip stabilisers and that's not good in the long term.
3. Flexibility - is that something you need to work on? Very few people are too flexible.
4. Crimping on small matchstick ledges is great, but think about the holds you are likely to encounter on routes at your grade: Pinches (wide and narrow), jams (ditto), sidepulls, mantles. All these are probably as important as crimping (if not more so), so again, get inventive (and alleviate the finger-boredom). It's not easy, but there's always something you can do to simulate these moves/positions/holds.
