Are the principles of interval training the same for everyone?
Yes — but you can take interval training to many levels. If you simply want to vary your exercise routine, you can determine the length and speed of each high-intensity interval based on how you feel that day.
After warming up, you might increase the intensity for 30 seconds and then resume your normal pace. How much you pick up the pace, how often and for how long is up to you.
If you're working toward a specific fitness goal, you may want to take a more scientific approach. A personal trainer or other expert can help you time the intensity and duration of your intervals — which may include movement patterns similar to those you'll use during your sport or activity — based on your target heart rate, the ability of your heart and lungs to deliver oxygen to your muscles (peak oxygen intake), and other factors.
Does interval training have risks?
Interval training isn't appropriate for everyone. If you have a chronic health condition or haven't been exercising regularly, consult your doctor before trying any type of interval training. Studies suggest, however, that interval training can be safe and beneficial even in people with heart disease.
Also keep the risk of overuse injury in mind. If you rush into a strenuous workout before your body is ready, you may injure your muscles, tendons or bones. Interval training doesn't have to involve high-impact exercise, ballistic or jumping movements, or heavy weights. Instead, start slowly. Try doing just one or two higher intensity intervals during each workout at first. If you think you're overdoing it, slow down. As your stamina improves, challenge yourself to vary the pace. You may be surprised by the results.
