'Interval Training for Fitness is the next best thing to having your own coach... it presents interval training as a complete programme for athletes of all abilities.' Carl Lewis

Interval training is an effective, medically proven technique that has been used by elite athletes for decades to add a special dimension to their physical conditioning. The training has three key components:

- interval training workouts: brief repetitions of intense exercise alternating with intervals of rest
- XL workouts: longer exercises once a week
- active rest days: exercise sessions at a comfortable pace to allow the body to recover

The programme:
- helps to burn fat
- gets results in minimal time
- requires no special equipment
- can be started straight away

Specific chapters outline programmes for beginners, intermediate and advanced exercisers, arranged in 12 week schedules. They include programmes for runners, walkers, cyclists and swimmers. Also included are tips for assessing performance, tracking progress, preparing for competition, dieting and injury prevention. Over 40 photographs illustrate the proper form and technique when stretching or using weights.
