HOW TO DO HIGH-INTENSITY IMPACT TRAINING
- Warm up for a couple of minutes until you are exercising at a moderate pace and gently stretching your muscles.
- Exercise as hard as you can (for example sprinting or cycling) for 30 seconds without stopping. This should make you breathless.
- Rest for up to a minute then do it again. Repeat three times within the space of five minutes.
- Do this at least twice a week. Make sure you see your doctor before starting a new exercise regime, especially if you are inactive or have a history of heart problems or breathing difficulties.
