Your muscles are already "developed" they genetically know what they need to do. You are not the first one to do this. Every human and all your ancestors did this it's obv when you put in "effort" it works.
This is why it is hard with psychic abilities because probably most of your ancestors could not do this at all. So you are either get "Lucky" with some "soul memory/power" which is deep within you and "realize it". Or... I cannot even describe what I want to say here. You probably have some "notions" how TK works already deep within you because you are quite obsessed with it (not an insult. When we want something there is usually a hidden "moving force" that wants us do it THIS WAY. You can solve so many problems without TK but you still want it there is a deeper desire for that.) The point is that your "TK muscles" are on "fetus level" so far. While a baby "grows fast" it doesn't really get "noticeable strength". You can differentiate between a 3 month old and a 5 year old quite easily but they still unable to lift anything that you would consider "heavy". The objects in reality are not just depend on their "weight" in TK but their "energetic handling" also matters.

Oh also "expecting the development" is also a sort of "hindrance". There is a sweet spot between false expectations that "deny" the manifestation and "true faith".

The best example I can give you is that you are expecting to "run faster" by "rolling on the floor" because you never used your legs yet.

Gambare btw. Your thought processes are on point. They just need to "calibrate" a "little further". Hard to shoot straight when we don't even see our target yet
