Alright I'm new to weight lifting, have no experience in this at all.

I do boxing and want a good balance of Strength, explosive power, and endurance(don't need to much endurance to be honest)

If I train with weights I do it in my shed, not in a gym. I have brothers but no one really wants to spot me.
I do boxing on Monday, Wednesday and Friday at 6:30 PM. I also have school most of the time from 8:45am to 3:45pm.

I'd like to have a training routine wich will allow me to build my strength in every part of my body. Not too interested in hyperthrophy, but I guess I wouldn't hurt to add some in the odd time.

I've read about these things called 5x5 Madcows. This program interests me, but I'd also like to do some 1rep max stuff if possible.

Also, do any of you know what I can do when I simply can't put the weight up on the bench? I don't want to die lifting weights so any suggestions for escape tactics when you're pinned to the bench?

Uhh...I have another problem aswell. How do I do squats when I have no rack and there's no one to help me?

I hope to hear from you lot soon, before I end up getting crushed by weights if possible :P
