This question has been bothering me for a while. Why would I ramp up? And why would I do straight sets? On a bodybuilding perspective, doing straight sets would allow me to do 3x10 reps with y weight straight, but if I ramp up, I'd go for (0.7y)x10, (0.8y)x10, (0.9y)x10 and yx9 (hit failure). So , on a bodybuilding level, wouldn't the straight set be better for hypertrophy since it provides more stimulus with more weight and more intensity?
On the other hand, ramping up gives more volume, combined with the final set (or two) to failure, could elicit greater hypertrophy gains? Or perhaps doing two warm-up sets of (0.7y)x8 and (0.8y)x8 and going out all out for (0.9y)x11 and yx7? Two high intensity sets now, but since the warm-ups would cause fatigue, would it not be better off doing a lighter warm-up and doing (0.9y)x13 and yx11?
So the question is, why is or why is not ramping up superior to straight sets, and if it is, what kind of ramping provides the greatest stimulation of the muscles for them to grow?
P.S. These numbers are only estimates. Not tested.
