So lil bro. We all find some kind of technique that just sorta "fits" us. The way we are all built is very different in various ways. Not just the shape but how our musculature is able to burst, what our power ranges are at different positions, and how much energy we can expel in a movement all go into making us unique.
Techniques group together and work differently on different body types. For example, guys with no neck are notorious for being able to avoid getting choked out while lanky guys can deliver KO power from odd angles and so on.
It's always best to focus training in techniques that if they don't work you are not in one of your more vulnerable positions. Lol ... A guy with a weak chin is not going to do well working inside the pocket with upper body strikes cuz he will get chin checked on a regular basis. Taking a nap 2 min's into a fight is not known as a winning technique. The weak chin guy needs to stay outside while working his lateral movement and look for freestyle takedowns like the shoot. If you have a solid chin, then you can work inside strikes and grecko based take downs from the hip.
Have you gotten far enough into your training to see where your going with that yet?
