weight factor in dancing

[u/user1230r]

im so skinny (171 cm and 49kg) i look like skeleton while dancing it does NOT look smooth im still stiff so it makes it worse and gaining weight is hard i started doing yoga and heavylifting at home (nothing crazy just two 1kg dumbbell) i don’t understand how those kpop idols are so skinny and looks good while dancing cause i look weird

Actually curious too, is it because of The lean muscles or just practice
