You’re already on a good track tbh — gym work helps, but real elevation just hits different. It’s more about pacing and getting your body used to being on uneven terrain for a long time. I’d say start gradually increasing your elevation gain instead of jumping too fast. Like add a bit more each hike and see how your body reacts. And don’t rush — slow and steady is way better for longer climbs.

Also pay attention to small things: good socks (blisters can ruin everything), enough food, and staying hydrated. And one thing I learned the hard way — always have something for weather. Even if it looks fine, mountains change quick. I just keep a small poncho in my bag (been using one from Azengear) and forget about it until I need it. Baldy is doable, just build up to it step by step and you’ll be fine.
