Sets that don't go to failure....they have to be somewhat effective, right? I've known a lot of pretty jacked dudes that work construction (concrete, roofing, framing, whatever). The ones I've talked to haven't been into lifting, they just go to work and go home.
All day long they're doing submaximal amounts, never to failure. But they're carrying around a decent amount of muscle. Obviously they are not as lean as we are, but they don't share the hobby. The muscle is just a side-effect of their job it seems like.
Just food for thought, and something I've wondered about for awhile now whether failure is really necessary in lifting.
Good observation.
Going to failure is not necessary but speeds up the muscle building process and can
help break through barriers to muscular size and strength. It been proven time and
time again. This is why I do not give a lot of credibility to the studies and so called
experts. (I have been training longer than most of them have been alive and
consequently experienced more, and seen more than they ever have.) Some good
advice . . . listen to the experts and do he exact opposite.
Again, going to failure is not necessary, example below:
If you are bench pressing alone and have zero safety deceives in place (like so many
did not long ago) where going to failure, the bar against you neck, was a tragic and
sometimes fatal mistake . . . you still made gains. I know I did.
Brutis69 wrote "volume is the key metric for hypertrophy according to pretty much
every study. not tut, not "muscle damage" not slow negatives, etc." Actually, most
muscle damage occurs during the 'negative' portion of the exercise and is largely
responsible for muscular soreness but I can give you some, but not many, examples
(leg extensions do not make you sore regardless of when, where and how you do
them) where that did not occur to me but that would be missing the point. And I
can give you many examples of where just negative exercise will give anybody
that is still breathing, is not half dead, outstanding results but will withhold
unless asked but is related to the original posters topic.
And to circle back to your construction observation, it remind me of something that
I read, was written 50 years ago, and still holds true in my small mind . . .
"Thirty years ago, it was noted that, "...the foreman of a crew of manual laborers will
almost always be the strongest man in the crew -- and he is the strongest because
he is the foreman, rather than being the foreman because he is the strongest."
Yet, in almost all cases, the foreman performs far less work than any of the other
men in the crew. A paradox? No -- on the contrary, simple proof of the effectiveness
of heavy exercise for the production of muscular size and strength. The foreman
works only when the combined efforts of the other men in the crew cannot produce
the desired result -- he helps to lift the heavier than normal load; thus his exercise
is brief and infrequent, but intense and irregular -- and those are the exact
requirements for producing the best results in the way of muscular size and strength.
Twenty years ago, the author noted an even more striking example of clear proof
of the same theory; the relative sizes of the two arms of an individual that has
been training with weights for a period of time long enough to produce marked results.
In almost all cases, the left arm of a right-handed weight trainee will be larger than
his right arm -- usually to a marked degree.
Why? Simply because the left arm of a right-handed man must work harder to
perform its share of an equally divided workload; it does not work more, nor differently,
it works harder, with a greater intensity of effort. And it responds by growing larger
than the right arm.
A right-handed man lacks some degree of "feel" in his left arm -- his balance and
muscular control are both less efficient in his left arm, and this remains true to
at least some degree regardless of the length of time that he has been training both
of his arms in an apparently identical manner.
The left arm works harder, so it responds to this increased intensity of effort by
growing larger, and in tests of strength that do not involve balance or muscular
coordination, the left arm will almost always be stronger as well as larger."
But when I have pointed this out to individual weight trainees as I have done on
repeated occasions the response had almost always been along exactly the same
line; "...well, in that case, I’ll do an extra set of curls for my right arm then it
grow larger too."
Having missed the entire point, they assumed that "more" exercise was required
when in fact, this situation is clear proof that all that is required is "harder" exercise.
