When you’re on the treadmill – or even running outside, for that matter – do you do the same thing every time? The same route, the same distance, the same time? While your consistency and disciple is certainly admirable, it might actually do you a few favours to vary your workouts.

“Variety improves your fitness by not allowing the body to plateau,” says Kerry, “and it allows the body the opportunity to adapt to the training. It will also help improve your stamina and strengthen muscle groups.

Most of all, it’s mentally more enjoyable and helps with motivation to complete a workout.”

Remember: the added benefit of treadmill training is that you can play around with your speed and incline to create a solid interval programme. Kerry recommends the following interval workout for treadmill training:

Warm up: 5-8 minute jog

Run: 45 seconds at high speed e.g. level 8-10

Jog/walk: 2 minutes at low speed e.g. level 3-5

Repeat this 6-8 times

Be sure to check in with your RPE (Rate of Perceived Exertion) on a scale of 1-10, with level 1 being easy and level 10 being so tough you can’t speak. “A very fit person should aim to be at a 9-10 by the end,” says Kerry, “but someone just starting their fitness journey should aim to be at a 6-7 while they build it up.”
