It is true.But this isn't true at all. A beginner is still learning how to lift properly so they effort isn't going to be anywhere similar. This is precisely why I originally said I agree with his philosophy in theory but it doesn't apply for every case/person.
Because being experienced has nothing to do with it.
You can find thousands of examples online of experienced lifters with imperfect or bad form.
The form isn’t the question. The effort is.
If you have Person X who hasn’t lifted before, it may be a lot of effort to bench 90 pounds.
Person Y may be experienced and may be putting forth the same amount of effort…except it’s not 90 pounds, it’s 315 pounds.
You don’t get more effort with experience. It just takes more weight to require the body to reach that level of effort.
There’s a famous saying from Tour de France cyclist Greg LeMond when asked about climbing his bicycle up mountains: It doesn’t get any easier. You just get faster.
The point is, the effort doesn’t get harder as you grow more experienced. Both guys could be trying equally as hard. You just are able to lift more weight.
And as long as the intensity is there…and there is sufficient time to rest, the growth will happen.
