What better for muslce growth. Short break periods where you won't be able to use heavy weight. Or long break periods that allows enough time to recover to lift heavier weight. I am asking because of info I read that says more IGF is pumped out with the increase of lactic acid and short breaks are better for muscle hypertrophy.

It depends on your body mostly.

Some people thrive off of shorter rest periods and gain a lot of muscle.

Others need heavier weight and longer rests.

What have u experienced?

Ilift heavy with longer breaks when im working on mass but when Im cutting ill shorten my breaks to like 30 secs and lower the weight as needed

cosign,,I'm with Kaboom..

yeah i think it depends.... i have some friends that only wait 30 seconds while bulking.... i like to give it 1-2 mins

I used to do 30 secs but after playing around with the times, I usually do 40 to 50 secs for breaks in between heavy sets. With lighter weights, as Kaboom said, I too use shorter breaks, but 25 secs is the shortest time I wait between sets, any less and fatigue sets in quickly.

Always 30 seconds to a minute unless working out with a partner. One jumps on, the other jumps off & vice versa. Train quick, hard & heavy then I eat. LOL

There are different physiological responses to varying work to rest ratio's.

Hypertrophy is achieved in two levels.

One, your myofillaments increase in number and size.
Two, satellite cells "spill" their contents into the muscle fiber, increasing the size of sarcoplasm and intrasarcoplasmic organelles. They also contribute another nucleus to control a portion of the sarcoplasm and organelles.

Different w:r's will account for the different changes associated with hypertrophy.

What do you prefer? and what do you think is associated with the most hypertrophy?

[ZiR RED]

I prefer to optimize results by either training for increases in both at the same time, or graining to increase one while maintaining the other.

I train for both in the same workouts.

i start off with a big heavy compound exercise and take relatively longer breaks, going really heavy with moderately lower reps.

On the next exercise I slightly shorten the breaks and up the reps to 8 or so. As I go through the workout I decrease the breaks and increase the reps as I move on to the next exercise.

I've heard that the maximum time you should wait between sets is 2 minutes.

In one minute you've regained 92 % of your strength and in 2 minutes 94%.
Don't flame me, might be right, I might also be wrong. : )
