One&Only magazine quizzes Tanya Becker, the brains behind Physique 57 on the fitness regime taking New York by storm

Talk us through the Physique 57 concept – in your opinion, what has made this workout so popular?

We have the perfect formula, which we call Interval Overload: interval sets use your own body weight as resistance, and through dynamic exercises, your muscles are targeted and overloaded to the point of fatigue, then stretched for relief. The technique is results driven, effective and never boring.

Is Physique 57 suitable for everyone (post-pregnancy, sports injuries etc)?

You should always consult your doctor before starting any new exercise. That said, our technique is low impact, doesn’t jar your joints and we incor­porate many orthopedic stretches. Many physical therapists refer their clients to us. There’s no one particular group that benefits; our success stories say it all!

How does Physique 57 compare to the other iconic body sculpting methods out there (Boot camp, Tracey Anderson Metamorphosis etc)?

Since we opened our doors in 2006, we have seen women lose inches in a matter of weeks. The key is this: our philosophy and overall exercise technique is consistent but we keep our clients’ attention, and therefore retention, because we vary the exercises, vary the motivating music and the exercises are all low impact so they are incredibly safe. We have clients who have taken six classes a week for five years!

What can guests hope to achieve in the four-day Physique 57 retreat?

The retreat is a great oppor­tunity to jumpstart your fitness goals. We’ve had clients see results in as few as eight workouts. We offer six Physique 57 classes over the four-day retreat, plus we send you home with DVDs to keep you on track and motivated.

How can guests continue the programme at home?

We offer six Physique 57 Workout DVDs so that women and men around the world can benefit from this focused and dynamic cardi­ovascular program of isometric exercises and orthopedic stretches. To purchase the DVDs, please visit www.physique57.com
