How do you stay in shape?

I work one night a week at one of my 3 clubs but it’s the best out of the other 2 for earnings. I was told I need to “tone up” if I want to work every night. I’m 5’3 140 pounds and naturally curvy because of my Brazilian genes. How do you guys stay fit/ lose weight? Drop your routines and diets plz 🩷 I’m so determined to be able to work here full time
