The verdict is in: stop doing sit ups. Sit ups, side bends, and curtsey lunges are just some of the exercises trainers wish you would stop doing.

Instead, try boxing, physique 57, or any number of these workouts that burn serious calories, ranked by amount of calories burned.

In the interest of purging boring, ineffective workouts (I’m looking at you, sit-ups) in favor of more engaging ones, learn how to make running something you might actually do for fun (gasp!).

Lastly, registered dietician, Cynthia Sass, dishes on the deceptive snacks her clients don’t realize aren’t healthy.
