Worst Vice... Advice?

I’m looking to get some input on a problem with endurance I have. First some background. For about the First 21 years of my life I was what you would call… fat (to be kind:) At 5,11" I weighed in at 300lbs. At age 21 I decided to get in shape. Over the course of a year I dropped 100 pounds by cutting out carbs and adding weight training.

The following year I dropped an additional 30 pounds by adding cardio (3 mile run every other day). Aside from being pissed at not being able to see much muscle definition (too much loose skin) I was looking pretty good and feeling pretty good. 170 pounds… the skinny guy.

Unfortunately the past few years, fitness has taken a back burner in my life and I've put back on a few pounds. I'm at 230 and have decided to get back into the game this time looking more at strength vs. body weight. So far I�??m on my way and have trimmed 25lbs  (I was 255 when I started 3 months ago). Ok enough background on to my problem. 

The strength in my chest just does not last. I bench 200 and the first set of 10 no problems, the second set however I can squeeze out 3 if Im lucky and thats it, total failure. If I drop the weight 50lbs I can get 5 maybe then failure. Same with Flys, when Im fresh no problem but after a few reps�?� done.  

The other portions of my routine go fine Legs, Arms, back etc�?�. Im building strength. Any ideas? 

How long have you been training since you started back up? If its only been a week, you will need to give it some time.

There was an article on here a while back about this problem(rapid decline in performance during a workout) although I cant recall the name or author… Maybe someone else can. Maybe it was Scott Abel, but I dont know.

AIDS, probably.

How long are your rest periods?

keep lifting more sets and more reps, it will take time.

Penis dysmorphia.

I’ve been back at it for about 3 months now. As for rest periods in between sets I try to keep it to 5 minutes (or how long my work out partner takes to finish his set). I’ve also tried adopting a wider grip.

I had a friend who has been weight training for several years suggest that with the shoulder wide grip I was using I could be over working my triceps on the bench. That seemed to help a little (went from 180 to 200) but still quick to fail.

Oh and “Strong like Bull!”
