so to start i am 6'6", during my routine (killroy) i have been noticing a trend of my lower back giving way. this is in the handstand and extended planks (arms straight above the head plank hold on the rings). i know coaches lower back work and can do them all except youngs and did wall RLL 4 sets of 5 but havent found a way to get weights on my feet out here in the desert which limits things. what i am trying to find out is if there is some other exercises to help strengthen the lower back or if that is more a technique issue.
i know there are alot of holes, i wish i could send a video or something but it is not possible from where i am. let me know if there is anything i can give to help you understand my issue better. thank you.
