To be honest, I would avoid climbing gyms even if they aren’t closed.

Is there a way to do these on a fingerboard? For example: taking off weight and hanging for x minutes, while switching holds every 10 seconds?

Yes, exactly. I’ve been using the following routines to target different intensities. So far it seems to be working well. Early in my cycle I focused on ARC and Max. Now I’m focusing on PE. All are increasing in weight.

- (10) 6x 7″/3″ (1′) @ 40% of max hang (aerobic restoration and capillarization)
- (6) 12x 7″/3″ (4′) @ 50% of max hang (low power endurance)
- (6) 5x 7″/3″ (3′) @ 70% of max hang (high power endurance)
- (6) 4x 3″/1″ (2′) @ 90% of max hang (max strength)
