Quoted message said:Whats the difference say between doing
1)3 sets of 10 reps of preacher curls-maxing out on the 10th rep.
2)5 sets of 10 reps maxing out on the last set
3)3 sets of 5 reps maxing again on the last rep?
If the burn is pretty close does it matter how many sets, how much
weight you use? Are either of these going to make the muscle grow
faster, slower, bigger, etc?
You're doing more total work with #1, as someone else pointed out.
Also, to do 10 reps in a set the weight has to be lighter. And the set will
last long enough that you'll be drawing on a different energy system than a
short set.
Strength has many different aspects including muscle size, number of
contractile elements, how many motor units are actually firing, how
coordinated your CNS is. Lifting as much as you can twice trains different
aspects of strength than lifting much less 15 times.
Sets of 8-12 reps cause your body to build up the energy systems of your
muscle, which are bulky, so it gets big. If you're getting a burn you're in
this range. Sets of 3-5 build up the contractile elements and CNS, so you
get strong. (Except that there's a lot of crossover.)
Studies have been done on training with multiple sets over training with
fewer sets, and have failed to show that sets beyond two or three get you
stronger faster. That's why HST has you only do two work sets.
