Meredith Shirk is known for her quick, strength-boosting workouts, often demonstrated from the poolside of her stunning home or by one of her numerous trainers in the studio.
Here at woman&home, we've tried and tested the famous 7-minute workout, so we know she's a trainer worth shouting about. In this workout, which I discovered a few years ago when I was looking for the best core exercises to do at home, Shirk uses exclusively standing ab exercises to target the deep core muscles.
