My sessions can last anywhere from 2-4hrs and I train up to around 20hrs a week. If you ask around a few competitive powerlifters I'm sure you'll find 15-20hrs of training per week is not uncommon, and a lot of these peeps have families and full time jobs. Dedication is what gets you to the top of your sport though.
First off, the guy in the vid is a knob.
Second, he's not a powerlifter. Or, by the looks of him, a bodybuilder. He's a PT. And you know what most of them are like. Cough.
What he said is, in essence, true, except he did the usual "weak, skinny, lots of certificates" PT shit of spouting off about stuff he knows nothing about. He was probably quoting from one of his textbooks. Or an ab machine ad.
Yes, a powerlifting program will take longer than a bodybuilding program. They are different. A bodybuilder trains to get bigger, a powerlifter trains to get stronger. Certainly not "more explosvie". The explosive bit comes later, in the leeeeerve shack. Bodybuilders (and please excuse this very rough and abbreviated statement, don't get yer lifting straps in a wad) train the muscle, powerlifters train the nervous system.
The result, if you look at the extremes, is a guy who is 170-180cm tall who weighs 120kg and looks "faaaabulussss" at 3% bodyfat, while a powerlifter of the same height may weigh 66kg and pull a 4x bodyweight deadlift.
A bodybuilder "can" train for 45 min and a powerlifter "can" train for 90 min. However, if you are serious, I doubt that either would train for that short a period of time. You think Heath/Cutler/Coleman/Yates et al train for 45 min? Pfffft.
Like Freako said, a normal powerlifting program for someone who is a serious competitor will take at least 2-3 hours. It takes me just half an hour to warm up. Depending on the lift, I can spend an hour just getting the main work sets done. Then there are accessories after and post workout prehab.
I must concede I am not a power lifter, don't do this professionally, and I do have a life outside the gym and training.
If you are a competitive lifter I guess you will probably have a greater commitment, than some guy who just trains for fun and general well being.
Absolutely. If you are not a committed bodybuilder or powerlifter, and want to look like that PT, then what he said is true. But then you would not really be either. You would be a guy who just goes to the gym.
