interval run
The best way to incorporate running into your exercise routine is to do interval running.
An interval running plan alternates between periods of intense, fast paces followed by less intense recovery periods.
If you’re new to interval running, start with a set of six 200 metres at a 5K pace, with an easy 200 metres in between each to recover.
