Look this is where confusion begins, thats why i say anything new and your not sure about it, best to stay away. Like the Hadith suggests.
At the end of the day ask yourself, what are we hear to do? Worship Allah and praise him? am i write. Now the way we worship him and invoke him has all been told to us. These intense Dhikr and stuff are just add ons, your Islam will not be inhanced by it. The reason why i say this is bcoz there is no evidence to suggest that by chanting Allah-hu on its own will gain you any reward. Rather when you say Subhanallah, Allah-hu-akbar and Astagfirullah, then you will gain rewards because this is backed by evidence and our Rasool (peaece and blessing be upon him) always with every breath used to utter Astagfirullah.
When you start saying Bhidah? and start looking at well is this a good innovation? Thats when things start to get complicated. Keep it simple and you will find that sometimes doing to much is a bad thing.
