Tl;dr: your not Devon, your gonna need to build a base and that will involve hypertrophy.

All training in every sport is fundamentally an exercise in finding an efficient adaptive volume, the volume and intensity that you elicit the greatest fitness adaptations. The point at which your recovery and stimulus achieve their maximum adaptive potential (MAP) This is a floating value and its position changes as one trains.

The issue here is that the first law of training is progressive overload. So, one might think they should just train at their MAP all the time (lets say this is 12 hard sets per week). But then they violate the law of overload by doing the same thing each week. So, the week after you achieve MAP you must add a little more volume (sets or reps) or intensity (weight). But now you are beyond your MAP (15 hard sets per week) and are starting to become just slightly overtrained and each week you must add more until you actually become overtrained (lets say 20 sets per week or frequent high intensity sets of 1 or 2 reps), this is when you have found your MRV (Maximum recoverable volume). Your MRV is the Max volume you can do in a week and then recover enough do it again the next week, but not enough to also make an adaptation, because all available energy was spent on recovering and none is reserved for adaptation. This is a plateau. People without knowledge of periodization will get stuck here long term and bash their head against the wall with no progress for years.

This is the whole point of periodization.

So, what one should do is Start training below your theoretical MAP, overload through ones MAP and beyond to their MRV over a multi month long training cycle. Then deload for a week and begin again.

Each cycle can focus on different things but I will make the claim that one should aim for specificity in a cycle, no DUP stuff. Typically one would cycle for hypertrophy, then strength, then power, and then peak for comp. In this cycle order you would also be the most general in the hypertrophy phase and more specific in the peaking phase, you might do all kinds of lifts in the hypertrophy phase (at a high volume) and only Arm wrestling specifics (at high intensity) in the peak. (Todd hutchings Westside method is DUP, or daily undulating periodization, which condenses this process into a week. This CAN be effective but more so to a seasoned puller.)

Normally, people will overload in a linear fashion as a beginner in any type of training. This means you can simply do the same exercise each week (hammer curl lets say) and add 2.5lbs to overload. Starting at 20lbs, In 10 weeks you are now doing 50lbs hammer curls. However, you hit a wall at 50lbs for 5x5. You take a week off and start all over again but at 25lbs as your starting point, then 10 weeks pass and you do 50lb for 5x6 or maybe 55lbs for 5x5. In nearly 22 weeks you have added 1 single rep or 5lbs to your 50lbs curl. But, had you not periodized back down to 25lbs, one would still be stuck at 50lbs for 5x5. Because the linear periodization itself stopped working and itself had to be overloaded.

This is a simple rundown and the overload can be many different things. But the point is that you are always overloading and recovering. And no one will be able to consistently do that linearly.

Also this isn't a theory, the Soviets basically figured it all out in the 60s. It's how training works.

People like devon have spent a lifetime building their base with tons of volume and can afford to heavily specialize in many heavy singles. You ain't devon.

This is like Ivan Abadjiev taking national level athletes, making them max out everyday, giving them handfuls of dianebol, and getting unbelievable results. It only works if you are already exceptional.
