Training frequency is one of the best ways to get overall volume, volume is the key driver to hypertrophy, therefore higher frequency = more hypertrophy. People can dispute it all day but it just doesn't make sense to argue that once a week training splits are superior. A quote from i think Dr. Zurdos - PhD in strength and conditioning programming "If someone put a gun to your head and said you had to put 100lb on your squat in 12 weeks, would you squat once a week?" instinctively the answer is no, but people try to claim it's optimal anyway. Also, there is a training response that induces adaptation with each set we do, this training response diminishes with the more volume you do in a single workout, so say you get a 100% response from your first set, you'll get an 80% response from the next, then 60% then 40%, if you come back and hit it again in a few days when the muscle has recovered, you get the 100% response again. But if you wait a week, and plan on getting the same amount of volume in (remember volume = hypertrophy) then you get say a 280% response from these 4 sets once per week, or do two of them twice per week and you get a 360% response. This is just random numbers, but you get my point. On a side note, i'm not arguing that people don't get great results on single body part splits/1x per week splits, but there's a big difference between what 'works' (almost anything 'works') and what's optimal. Lastly i'd recommend watching 'biolayne' on youtube, he has a lot of really useful videos on this type of stuff citating studies and articles that are up to date and valid.
