Have any excercises for my dance leaps and turns?

for me to get stronger in legs to jump higher i do about three lunges then jump my highest on my left leg and then my right and then in the front and i do it over and over and to get strength in my legs i do leg lifts and i lift my leg up and hold it there for as long as i can without bending my knee and keeping my alignment straight and for turns i would just say keep practicing them over and over and splits the same
