Had super bad elbow tendonitis in left arm... rehabbed, had a busy life... eventually returned. Very quickly unearthed equally bad issues in right arm (yes, I returned slowly/easily, but nonetheless it happened, mri had an almost full thickness tear in right arm extensor.)
Rehabbed right arm, and have gotten back to it. Mostly focused on re-gaining strength and bouldering after an initial easy break in period.
Anyway, as the fitness/training world seems to change with the winds - after 2 years off - what would be the current standard practice for regaining route fitness, without wasting time? I'm familiar with the Anderson bro's approach, Alex Barow's writings, lattice.
Basically - have things changed much? I don't want to waste time randomly "just climbing" - I'm sure when I return to leading, I'll get gains for a while just by virtue of not having a base anymore, but would rather just start structured. For reference, formerly a consistent high 5.12's climber, but obviously any previous route pyramids or what I've done are kinda moot and would need to be re-established.
