Training Routine: This 4-Day A Week Routine Is Based On Working Until Failure.

I try to base my workout on failure, which means in bench for example, I may do 5 sets of 5 with 275 today and complete the bench workout. Next week I will move up 5 pounds to 280 and will most likely not complete the workout without being spotted. Once I do, I will move up again. This keeps me working at my peak and allows me to see improvement.

I am looking for additional lifts to this workout and comments on what you think about this workout. Also, I am very soon going to be upgrading to a 5 day workout and I'm looking for suggestions for a fifth day. Thanks
