my bench pressing hasnt improve in over a month, altho I do it every other day, I dont know what is the problem but I just dont have the strenght...
If you are bench pressing every other day you are probably overtraining your pectoral muscles therefore you are seeing no increase in strength, try bench pressing once a week with low reps of around 3-5 and keep increasing the weight slightly every week and you will see an increase in your bench press over a period of time
stop benching all together for a month. focus on building your back and shoulder strength. then come back to the bench and hit it only 1-2 times a week. that worked great for me when I was in high school and I plateaud
switch to dumbbells, presses and stop doing it every day you are not giving your arms the rest they need do other things like curls then legs then triceps then stomach then chest and so on rotate them so you do not do work your arms on the same day or the next day same with chest as you have to use your arms for this ok. also go up in weight like start with low weight and move up 5 lbs at a time, till you hit max. also do 5 sets of 10 reps or better cause this will build strength and endurance.
