Good to be reminded every now and then.
Actually this video seems basic and nothing new in theory and probaby every other amateur athlete out there knows this knowledge. issue is that in reality, still a quite a fair number of cyclists / runners / swimmers fall into this trap once past the beginner/base phase or even intermediate phase. Coz it is not a pretty story when you are doing it in real life.
With strength or calisthenics it's much easier to see this at work than cycling or runner, coz to track the improvement with reps is a much more instanenous result that you get than your runs or cycling sessions, as you increase weights/bands thickness/ how much you shorten it etc.
Coupled with proper recovery, i am still seeing gains in weighted dips but i don't really change the number of reps as i feel comfortable in a certain range. Pull ups a bit difficult, i can only rep/pause it for variation....unless i find a way to hook the band to the ground. lol (still cant manage high pull-ups and those stuff)
Remember, it never gets easier as you get faster/stronger. It's supposed to "stay the same as when you were beginning in this sport".....ie the workouts are supposed to feel "shocking". But of coz you need to pay attention to proper recovery/nutrition etc...coz these would change as well as you progress.
