but I was trynig to leanr more about the benefit of adding volume more than the the best way to increase lifts.
Volume over intensity has its place. It can be goal dependent, individual dependent, and situational dependent.
But keep in mind, volume for the sake of volume is doo doo, and often why I think people feel it is useless. Doing sets of 135x20 with BB shrugs once a week for a year, is going to have jack for carry over. Now going from 135x20 to 495x35 in that same year, is going to have a TON of carryover. You can't just pick some non-challenging weight and do 800,000 reps with it and expect magic to happen because you call it volume. Just because you are doing 2x20 or 6x6, or 18x2, you still, above all else, have to be increasing the loading over time, whether that be TUT or raw weight on the bar.
Some benefits of volume:1) Tends to produce more size gains,
which give you better leverages. Better leverages = bigger numbers = stronger you = more size gains. A strong muscle can become a big muscle easier, and a big muscle can become a strong muscle easier. It is a chicken/egg situation.
Any one person can get from small and weak to large and strong either way, it will be individual dependent for a couple of reasons. Once you "get" that, the questions on volume are easier to answer.2) Volume is easier to recover from. Now
Now if your work capacity, diet and endurance suck, this won't be the case. But once you get to the point where you banging heavy ass weights, and I'm not talking about relative strength here, I'm talking big numbers, your joints and 'CNS" (T-Nation has ruined CNS for me, hate it now) just can't take working in triples in all the lifts all the time over months and months. Why do you think Deloads are programmed? Because most people aren't smart enough to pull back naturally, so authors write it in. Taking a couple weeks/months whatever to focus on turning your 8RM on bench into your 12RM will, in fact, most times, increase your 1RM. Look, elite level powerlifters lift 2 and 3 times a week, because they need more time to recover, and are on as much gear as the elite level bodybuilders that are hitting a bodypart twice in 6 days, and training 5-6 days a week. (You are deluding yourself if you think they aren't all on the same amounts of the same types of AAS.)
I also wonder if it depends on the proximity of your goal. Say if you have 10 lbs on Bench to increase, for 5 reps, or say 30 lbs. Now, will you be best served in the 30 lb goal to mix in some volume to "build mass" or is that type of muscle not really going to help.
Of course it will help, lol. Weight moves weight. Why do you think the strongest powerlifters in the world are fat as hell? Weight moves weight. Bigger muscles are stronger muscles, and also add to leverages, which means bigger lifts. Fat adds to your leverages too.
Now getting fat isn't going to magically make you a 500lbs bencher, but, it will get you over a 10lbs plateau
ON a broader topic other than Volume, I would guess there are strategies that work better for
^ is finishing your quoted statement. You have to do what you enjoy, what you feel works for you in your schedule and your goals.
