Guys this might be controversial but demon's method of training extremely hand focused brought the best results for me.

After following devons regiment of hand focused training for about 7 months. I turned to levan's method of training of more standard lifting. My arms and everything else got huge, but my armwrestling strength fell down a lot. So I will return to Devon's method of hand focus more for a few months and I will tell the results.

Edit: Devon not demon must've been high
