As we get older we get smarter. Same style of training I learned from Ron Love. His training philosophy I endorse 100% and recommend it to all aspiring bodybuilders.
the core of his "philosophy" is most likely to shoot up drugs regurlarly and the training part is probably not rocket science
Crazy to watch him train and then watch Branch and JOJ. Tony does look good for his late 40's.
I'm still relatively young at 25...so I like doing one balls out heavy exercise (bench, deads, squats), and then a plethora of these pump sets after that like Toney does. Seems a good balance.
Once you get injured, God forbid, you will have to train smarter. No benefit in going heavy.
My routine is pretty modest with only one heavy exercise; not like Branch who goes HAM for 35 sets. You really think you can't do the Big 3 lifts for sub-6 reps into your old age?
Id imagine the one arm dumbbell press would feel awkward. Would probably take some getting used to.
