If I am stuck with a weight on an exercise for a few weeks (considered that my diet and rest have no problem), does that mean I have reached a plateau? If so, how to break this plateau?
For example, for incline dumbbell press, I can do 12 reps with 20lbs, 30 and 35, I can do 8-9 with 40, and 5-6 with 45. I do all those by myself. I know that, for every next work out, I should increase a little bit weight or do a few more reps that what I did last time. But for a few weeks, I can neither add more weight nor do more reps. What should I do?
If I ask someone to spot me to do 1-2 more reps than the last time, does that work?
Thank you for any idea.
