What is Pilates? An exercise technique that was invented for injured dancers nearly a century ago by ex-carpenter and gymnast Joseph Pilates. There are two ways to practise Pilates (pronounced pih-LAH-tees). You can join a mat-based group class where you'll do specialised calisthenics exercises, or you can take private lessons on a series of specially designed machines with exotic names such as the Cadillac and the Reformer. Whether you take the mat class or use the machines, all Pilates moves are designed to work your powerhouse muscles — abs, lower back, thighs, and buttocks — and to gently lengthen them. The result is a body that is properly aligned and at less risk for injury. Not to mention, practising such exercises on a regular basis can help you move more freely and gracefully.

Why we love it: Pilates increases strength, flexibility and endurance. It also improves posture, alignment, co-ordination and balance without bulking up your muscles. In Pilates, nothing is forced. You emphasise correct form rather than going for the burn.

Drawbacks: It can be expensive. Private lessons will set you back £22 to £75 a session depending on where you live. By comparison, mat classes are a bargain, running £8 to £20 a class, again, depending on the instructor or part of the country you're in. Check out whether your gym offers classes to members at no additional charge or private instruction at a discount. And be aware that if you like to master things quickly, this may not be the workout for you. Like dance, yoga and martial arts, learning Pilates is a long-term, evolutionary process.

The following curl-and-lift move gives you a taste of what you might experience in a Pilates-inspired workout.

1. Lie on your back with your knees bent, legs pressed together and feet flat on the floor, hip-width apart.
2. Contract your abs and hold your arms out at your sides and slightly off the floor.
3. Moving slowly, curl upwards until your chest touches your knees. First lift your head off the floor, then your shoulder blades one vertebra at a time. If necessary, assist yourself by holding onto the back of your thighs.
4. Sit up straight at the top of the movement then round your back and lower with control.
