You might just not have the structure for it. There really isn't a need to go really wide - regardless of what fitness influencers say. A shoulder width pull-up will work the lats just as well as long as you go to, or close enough to failure to stimulate a response for muscle building at rest.

Frequency is going to be better than intensity. Alot of those 20 sets/day are going to be junk volume anyways, and cause longer recoveries.

Intensity matters far more than volume. If you are training to momentary muscle failure (actually training to it) you can do it with 1 set. I would probably hit the target muscle again 3-4 days later, but it will be based on your ability to recover. I normally recommend the average person do 3 sets in a workout because unless you are with a trainer or someone who understands what failure is, you most likely aren't getting there and stopping early, cheating, etc. You may also be doing it in a way that is unsafe. If you are just starting out and learning an exercise, then do multiple sets and just focus on form before moving to progressive overload. All you need is a great enough stimulus for the muscle to tell the body it needs to build more at rest. If you leave reps in reserve, you will need multiple sets. If not, you won't. If you do decide to go a high volume route, I recommend splitting it up. Doing a lot of sets of a single body part on one day will just lead to a ton of junk volume as the initial sets (or later sets) aren't doing anything but creating a deeper hole to recover from. Some people have really good genetics where they recover quickly, but the average person does not. Also, anabolics would help speed up recovery, but then you get into the not natty territory.

That can work, but the goal is to make things as simple as possible. The average person won't be tracking 20% this, 20% that, it is much easier to just try for a target of protein, then fill in the rest within your calorie goals.

Haha making his way in front of my videos. C'mon KZfaq.
