But this is serious. I started weight training a few months ago, after a long break ( 5 years ) So now I have a specific "problem" When I do benchpressing - I warm up and before starting the real weight I do like 30 pushups then rest 2-3 mins then I make 10 reps with 170 pounds to warm up and then I do my sets with 200 pounds 9 -10 reps which is at the moment the max I can do, like when I do the 9th rep I know I cannot go another one, impossible ! I train with that weight for about 4 weeks already, so I thought if I can do 9 reps with 200 pounds I should be able to do like 11-12 with 185 pounds. But I can do only 9 -10 reps just as if its 200 pounds. I thought maybe I had a bad day or I lost some strenght But I can do the 185 pounds as much as the 200 pounds I tried several times.. So WHY is that ?
