Hey Everyone,
As most of us normally do, I have been consistently gaining strength ever since I started working out (4 yrs ago?). This past spring I finally broke 300 lbs on the bench and up til about 6 weeks ago I have been able to consistently do a few reps at 295 to 310 depending on how I feel on a given day. However, over the last 5 weeks I have lost a ton of strength. I maxed out a few weeks ago at 270, then a week or two later I couldn't do more than 255, then the other day I barely pushed up 225 after 4 reps! This is not normal for me, I could bust out 225 for 12 a year ago. I can't figure out where/why I am losing all this strength. Other than super pump, protein, and multi-vits, I don't really take anything. I haven't changed my workout, diet, or sleeping patterns that I can link this loss in power too. I'm only working out 3-4 days a week so I don't think overtraining is an issue.

Any input that you can provide would be appreciated! Thanks fellas.

Sounds like you are overtrained, take a rest and get back at it.
