I think the extensor tendons of the fingers are under little strain while climbing. (I can move mine with the other hand while pulling 20+ kg in a half crimp position.) Does it still make sense to take a break from training when one has a slight extensor injury from an unrelated cut – slight enough that it doesn’t interfere with the hand mobility and didn’t cause problems during some, perhaps ill-considered, training sessions? If so, how long should such a break be?
