Hi! Been climbing for about two months (after a 10-year hiatus after climbing 1x a week for a year or so). What's your warm-up routine?

I usually stretch for 5-10 min, boulder easy (v1) - projecting routes (v3 / v4) for 20-30 min, and then top rope 1 easy route (5.8 for me), 1 harder route (5.10+ or 5.11-), and a project route or two (5.11+ or 5.12-)before going back down to harder routes and then do an hour of weightlifting when my climbing begins to get worse.

I'm wondering if that's TOO much warm-up time for working on projects and would love to hear y'alls advice!
