Rough guide based on published correlations between max hangs and grades. Technique, power and tactics matter just as much.

Are my fingers holding me back?

If your fingers test below the grade you climb, finger strength is a likely limiter and structured hangboarding pays off fast. If they test well above it, more hangboarding won't help much — technique, tactics and trying harder climbs will.

Kehity does this comparison automatically from your logbook, together with the styles you avoid and how often you actually climb at your limit.
