At Curves we strengthen women. The Curves workout has helped women in South Africa and many other countries get the results they need. The workout offers the benefits of a longer 90 minute workout, but takes just 30 minutes. The reason the workout is so effective is that it combines strength-training with sustained cardio, warm-ups, cool-downs and stretching. Research shows that the Curves workout delivers proven results - protecting muscle, burning fat and boosting your metabolism.
