@Ah Huat I have been training my core too cause I heard it helps with muscle ups. Also, I can do one muscle up with band support, but not without band. I do think it's the form thats stopping me from achieving it though.

@Nico Mauger yeah thanks. I really am bad at swinging. Maybe I could improve that.

@Daemon Caliversity thank you brother I will definitely try to improve my form

For an aesthetic body, I would recommend hypertrophy wokouts. Depends on your goals though, what are you trying to achieve? If it's only muscles, then train with the principle of progressive overload. Train major muscle groups and compound movement like pushups for chest, triceps and shoulders, pullups for back muscles and squats for legs. Those are the big three. You can add additional isolation work like bicep curls with bags filled with books. But stick to those 3
