So I am not an expert by any means, but I have been lifting for many years. You said you have been doing a high volume bodybuilding routine..I don't know what the volume was but its probably a lot more than what any strength training program would call for. Anyway, I guess if I had any advice to give, it would be to resist the urge to do much. In strength training I've realized you have to find that sweet spot of volume...if you want continuous gains, mostly because your joints take a serious beating when it comes to the heavy low rep work involved.
I could go in on Monday and kill my chest with a huge volume of heavy reps and sure my muscles might be ready by next Monday but my joints will not. By no means am I saying be a wimp, just be mindful it's a different approach.
The best thing I've discovered on the Internet (besides porn) is 5/3/1. I literally feel I've trained wrong until I found 5/3/1. West side barbell is great and all, I'm sure..but it didn't appeal to me personally. In my opinion anyone can get strong, fast or slow..obviously you are a "fast" person otherwise that statement wouldn't mean anything to you, and obviously it has some truth seeing your dead lift max...but a slow person can dead lift a lot too, so who knows...whatever.
5/3/1 to me is geared more to guy like me, who has zero time to be playing around in the gym..and I don't have 3 spotters at my disposal to perform super heavy sets of whatever with chains that are bigger than any chain Home Depot carries.
Any who, now that I've realized I am bias to 5/3/1 and that apparently think I know it all, I will stop talking. Good luck.
