I think some of the non purely physical performance training that could help out a LOT of people in both the Valley and in the Tuolumne/ High Sierras is efficiency. So many climbs/ objectives are much longer than anything else in the lower 48 outside of the PNW alpine, Tetons, Winds, and RMNP. So not only having things like belay changeovers fast, but being able to climb fast through sub 5.9 terrain is one of the best skills to have. So if you aren’t already good at running out sub 5.9 terrain that’s a good thing to train. That way for those harder alpine objectives you can have more time to burn on the hard pitches rather wasting it on the easy stuff before and after.
To expand on the “get good at crack” message that everyone will tell you is getting good at weird and funky cracks is super helpful. There are tons of that terrain in the Sierras and that’s another thing that will help out. So climbing poorly rated stuff because it’s awkward is good training imo.
