I don't know much about yoga but from what I have read on the internet I think the description of kundalini yoga is a little bit similar to qigong exercises designed for opening up and moving the qi in ren and du meridians(xiaozhoutian) and eventually in all the meridians (dazhoutian).
I am not sure how easy it is to find authentic martial arts masters outside of China as even in China there are very few of them but in internal martial arts like taijiquan, xinyiliuhe, baguazhang, ... they usually teach techniques to their indoor students for opening the meridians and using the dantian energy however it usually takes many years of training to achieve these results.
