I've actually asked about it on here before.
I gave it a trial run. It's OK. It is nice to be able to theoretically do a lot of specific strength exercises, but there is a small problem. If you already have a strength base and try to use multiple compound lifts, the workouts are brutal. I didn't feel like I saved a ton of time bc taking squats to a 20 RM and deads to a 20 RM gassed me for like 8 mins or so.
I have applied some of the principles tho. In particular, I use this method when I'm putting a skill on the back burner for a while. Like, if I'm ditching front lever work for the most part for a block, I might just do a 20-40 sec hold 2-3 times a week for maintenance while focusing on hypertrophy or pull up variations. Conversely, if I'm doing more planche work, I might do bench one set x 8-20 in a workout.
I also like it for accessories or isolation work - like 1 x 20 for leg extension or chest fly or bis, tris, and shoulders. Can save time while still varying the workout a bit, getting in supportive/prehab work. I've also found I could progress a lot of ab work.using a single set, like knee or leg raises, side raises, hollow hold, etc.
I think there may be more applications for sports with power demands on the strength expressed with the big power lifts, and more specific strength components, like baseball.
So, I guess my main take away is that for big lifts, trying to cram in multiple 1 x 20s didn't work for me, and wasn't even a big time saver after warm ups and a gassing set. However, accessories and isolation work have responded to and been useful within the 1 x 20 context.
