It’s not a good idea to attempt a particularly challenging workout when the weather is hot. In fact, it’s best to reduce the intensity of your workouts or break it into chunks to give yourself extra breaks, as well as reducing the overall time you work out for.

You’ll see the most benefits from working out in the heat if you’re able to gradually acclimatise your body to higher temperatures, so it’s best to practice exercising when the temperatures are in the low 20s, before throwing yourself into a HIIT class on the hottest day of the year. Although this might be difficult to plan with the UK’s notoriously unpredictable weather.

Plus there are a few things you need to remember about exercising during a heatwave to keep you safe: “Hydrate frequently and if you’re exercising in the sun, wear sun cream,” Margo advises. “Avoid working out at the hottest times of the day. Instead, aim for morning or evening workouts.”

“Know your limits and listen to your body – if you feel exhausted, sick, or dizzy take a break or cut your workout short,” she adds.
