I believe I'm reaching a plateau - I went from using a standard 3x10 set combo for the flat bench press to using 5x6 (for 30 total reps). I could not complete 180lbs @ 3x10 but was able to do so quite easily when I switched it up to 5x6. Am I cheating myself out of muscle progression by changing my set/rep combo?
Advance to 185 using 5x6 or stay at 180 until I'm able to knock out 3x10?
I'm 5'9" 165lbs if it helps to answer this question.
