Before I forget about this post I wanted to post numbers in a hypothetical scenario
Say you take your last set(since it will be the hardest) and it looks like this over time
195x6 etc etc
And you stall out sometime down the road at say 225x6 and a couple times in a row you can't add weight or add reps then pick a new exericse(not sure what bodypart you were referring to) but if it's flat bench press maybe go to incline presses or dumbbells or a HS machine and bring that one up in strength till you top out. Training like this will make you strong and not OCD adjusting everything you can every month like many beginning trainees. Write down your numbers each time and when you repeat an exercise do at least a little better everytime and those little betters will add up to a lot better come months-years down the road. Oh, and eat a lot of food or you won't see these increases.
