Whether you prefer a high waist, medium waist, or low waist; it all depends on your taste, style, comfort level, and preferences. It has been proven that a higher waist seems to be the most comfortable because of its ability to hold everything in (in case one is conscious of their core) and also make you feel secure during HIIT workouts without any fear of the pants slipping. Moreover, a higher waist also provides more coverage if you want to pair it with a longline bra or sports bra to complete a outfit.
