Welp, still working on this one... I'm pretty sure now it's actually the push ups that are causing me the problems.
Been working on the pull-ups and I've reached 4 sets of 4 full extension :D
Move to pushups and my elbow fails after 5... yes, 5. At least I've learnt stop and recuperate when that happens now (damn there goes another week).
Has anyone got any good subs for push ups? Any neat tips on style/hand placing that might reduce the strain on the outer edge of my elbows?
