How many grams of protein are you taking a day? I take about 120 grams plus whatever I can consume in food. Genetics may be taking over. I'd just try to keep upping the weight everytime you workout and do less reps. Do 6-8 reps with more weight than usual instead of trying to do 10 reps with less weight
