Ok, for the past couple of months I have been following the workout below with good success.

I'm progressing nicely and seing some good gains, and would like to change my program in the next couple of weeks or so. I'm 5'9" 175.

I have a home gym with the usual, bench, 300lb plate set, a few pairs of dumbells, treadmill, swiss ball & chin up bar. A limitation that I have is that I can only squat what I can get over my head, and I also do not have a spotter. Given those limitations, I think a true 5x5 program will not work for me. I've used it before in high school, 10yrs ago, but know that I can't truly follow it now given that I don't have the proper equipment.

Any suggestions? Thanks for the help.
