I was wondering this today. I know its typically accepted that more volume will equal more size with a given weight, but im starting to question this.
Here is how ive been training lately, and what led me to this line of though:
For my main compound lift for strength, ive been keeping the reps under 5 with shorter rest breaks. Usually it is something like 14x2 with 60 seconds rest. But I also have been using 7x2 with the same rest.
Now lets say this was one of those identicl twin studies.
Both twins start by Squatting 300lbs.
Twin A does 14x2 with 300lbs and keeps increasing the weight when they can get all sets
Twin B does 7x2 with 300lbs and progresses the same way.
After a few years, they both reach 600lbs for their workout, and they both have the same 1RM.
Would there likely be any difference in size between the two guys, or would they be very similar as they both had the same strength? I guess this is a question of whether the workouts lead to the size, or the increases in strength lead to the size.
I could see how Twin A would be bigger, because he would have the same 1RM but would probably have a greater work capacity, but im not sure about this.
The only problem with this scenario, is I could see that along the line, either twin might need to change their volume to continue to progress.
Ex: Twin A might need to reduce the overall volume because as the weigh increases the stress from the same number of sets might become to great.
Ex2: Twin B might need to increase the volume, because he might get to the point where he can handle 7x2 with something like 500, but can only do 2x2 with 505 (im not sure how likely this is, but it seems like a possibility)
Im thinking if the both hit the same strength level they’d both be the same size. One method might lead to a person reaching that strength quicker,but once they are there, I think they’d be the same. This may support the idea that it doesn’t matter what you do, as long as you increase your ability to lift weight.
I dunno what do you guys think?
