I really enjoy listening to his explanations of single-joint biomechanics.
I just can't get that way of training to make sense from where i'm coming from. If I look at it from another perspective, ignore "Movement", and squint a little, I can see the value in it. If I think of the body as a collection of single joints vs one unit, it makes sense. Basically, for me, it's Biomechanics through a bodybuilders lens.
I can't see the value in it from a rehab perspective, either. In fact, particularly from a rehab perspective.
If you had a client who was quite old and quite injured, then you could argue that with his method of training people, it would be difficult to make them any worse, whilst still allowing them to get some exercise in and feel better about themselves which, in reality, is miles better than most personal trainers, who would almost always make things worse in this case. Super slow partial ROM (mostly) machine based training is unlikely to do so, at least not for a while, anyway. This is where i'm able to see value but, it's my personal opinion -not fact - that this also takes personal training a step back rather than forward.
In my mind, the thought process of "not making things any worse" just doesn't work. I want to make people better.
Also, if someone is that injured, they don't need a Personal Trainer, they need a medical professional/physio/whatever. If they're THAT bad, then the trainer should refer out.
I think banged up clients are one of the biggest problems in the personal training industry. Trainers for the most part aren't equipped to deal with injured people. However, more and more people are injured, and a lot don't even know it until they step out of their comfort zone and try out some exercise - and this is where Quasimodo decides to deadlift, hurts his back, and goes on internet forums warning everyone not to deadlift, because, "look what happened to me?". I think Trainers can either go 2 ways with this. We take a lot less risks, dumb everything down, and create training methods where it's almost impossible to suffer "catastrophic injuries" (overuse is another post). Or, Trainers get a better understanding of how the body is supposed to move, get better at coaching things properly, get better at understanding what people "need" vs what they "want" and as such, get better at writing programs, get better at knowing when this isn't a trainer thing anymore, it's a medical professional thing and use methods to try and control, predict and manage risk.
I'm probably more of an idealist than a realist. Maybe Bill is real and i live in a dream world. For me there are some amazing things happening with the industry just now. I think the Training world and the Rehab world are learning from each other and working with each other, which means both perspectives can follow the same "rules" - we all move the same whether you're training, seeing a physio, or seeing an orthopedic specialist. Movement can be measured, it can be managed, it can be improved, and boundaries can be set, and all of this can and should dictate training and more so, whether that person should even be training or not.
You need to make the car road worthy before you put it out on the track. Take a problematic car that isn't road worthy, only allow it to be driven slowly, no harsh acceleration or breaking, and no crazy cornering, and yes, you'll get more miles out of it.
However, if you either dismiss or don't understand the importance of Movement, then none of this will make one bit of sense. I think that's the problem.
If you take the same older and injured client mentioned earlier, and you think movement, and think Joint by Joint approach (which to me is, "the rules"), then most of what is "Congruent" doesn't make sense. A leg press doesn't make sense. I couldn't justify putting a slow tempo leg press or pec flies or slow bicep curls into that persons program. Frankly, if I was training that person in conjuction with the physiotherapist I work with, he would most likely verbally assassinate me.
I have the same criticism for physiotherapists who disregard the training world, btw. I think that's just as bad (a step back, rather than forward).
