I've been struggling with the back lever lately -- right now I'm at a pretty solid tuck BL but can't seem to move past that. First, my BL is way behind my FL (can hold a solid straddle FL for a couple of seconds, but can not even get into a satisfactory adv. tuck BL), which I know is usually the other way around: has anyone had any "aha" moments or technique tips that made the BL easier that I may be missing? I've noticed it can be made slightly easier by "pressing inwards" with my shoulders towards a more concave chest, is this ok to do or bad form?
Either way, it seems to be my back strength that is preventing me from moving forwards (I am also not very good at press handstands -- can barely do one straddle press HeS) -- would press headstands be the best way to improve lower back strength or is there a better exercise for helping the BL?
Thanks!
