Interesting, yes momentum for me is usually about ego and has caused acute injuries as well as playing into wear and tear on my achy joints. I don’t know that Boyer would have been able to stop at just any point during the motion on the way up, as he used some explosive force. Do you think the ability to stop at any point would negate explosive type reps? Would definitely cut down on the weight able to be lifted as well as the number of reps for said weight. Did he use any type of count?, say 3 down, 2 count up? Thanks
I have not looked at the video recently, but I think Arthur may have used something
called a 'pre-stretch reflex' here. A pre-stretch reflex is something akin to baseball
player bringing his bat back just slightly before executing a swing which recutes more
fibers. Same thing for a golfer or when somebody jumps, you dip a bit before jumping
or when you go to punch somebody, you rear back then a bit more before you bunch.
Many other athletes do this which I think do it instinctively with out knowing the cause
and effect relationship I suspect but do know know.
This can be used very effectively in weight training (you see some bodybuilders do
this, Jay?) do this to some degree. But it must not be taken to extreme as it can be
counter productive. Do it just a little and it can be very productive.
Truly explosive movements have no place in weigh training and can be dangerous
if taken to extreme. There are many examples of this so I won't go into detail.
Stopping at any point during the execution of an exercise is safe but I do not
know if it "would negate explosive type reps." Again, a slight amount of a pre-
stretch reflex can and is helpful.
As far as the speed of movement, there is no secret cadence. As long as the weight
is under control, you are good to go. But accentuating the negative part of the exercise
is productive. I believe he said, is more more productive. Again, not 'super slow' as
some advocate is not the way to go with the exception of negatives, which will help
break through sticking points in training, especially in regards to negative only exercise.
I do know a man that added one inch to his arms just be slowing down the negative
part of his curls and triceps exercises. That was all he did to get that extra growth.
More on that when I post up some interesting examples of negative only exercise.
