Crazy and inconsistent earningsI

Started a routine a little over 2 months ago, I tested several different things and got good results, I don’t have a right routine but I always do 4 or 5 days on and 2 or 3 off depending on the stress caused, my focus is BPFSL I’m thin but I have a little fat in the bone region.

Start BPFSL: 15.5 cm Currently: 17.3 cm
