When I climb outdoors, I climb two on one off (with the occasional double rest day). For training, I think every other day works well for me (with the occasional double rest day). A lot of the climbing-related things I need to do can be done from home, so when I don’t feel like I have the time for actually going to the gym, I will work do a mini core work-out and then work on flexibility for an hour or so (for example). I’d say, keep a detailed log of what you do and assess it after a month. Looking back at that month might really help you see what works for you and what doesn’t! I just started logging my climbing days, workouts, with a ton of details and it’s a bit mesmerizing.
