With the announcements of group outdoor exercise being allowed from 29th March, and gyms reopening (7 weeks and counting, people!) temperature specialists Stelrad wanted to ascertain the perfect temperature for a fat burning workout.
50 volunteers were given Fitbits and asked to do the same 20-minute HIIT workout. They did this workout once a day for 8 days, in different temperature conditions each day.
Calorie burn was measured on the Fitbits, and the participants were asked to record if they felt their exercise performance was hindered by temperature.
- Contrary to popular belief, a hotter workout temperature doesn’t mean more calories burnt
- The best temperature to workout in terms of calorie burn is 20 °C
- Gym’s in the UK normally have their thermostats set between 16 – 18 °C, therefore NOT maximising calorie burn potential!
- The most comfortable temperature to workout is 15 °C, with 0% of respondents reporting temperature related discomfort.
- The lowest calories burnt were at the highest temperature of 40 °C.
- Temperature experts at Stelrad said “At a higher temperature your body has to work harder to keep your body cool, hence burning more calories.
- However, when you’re too warm, you are unable to workout at the same intensity.
- Therefore, it’s important to find the sweet spot where your body is warm and burning extra calories, but you can also go full throttle with your workout”.
Full Study Results:
|Room temperature °C||Average calories burnt||% of respondents who felt their performance was hindered by temperature-related discomfort|
- Stelrad provided 50 volunteers with Fitbits
- They were asked to complete a 20-minute HIIT workout each day, for 8 days, at a different temperature
- Air conditioning and heating were used to create the desired daily workout room temperatures
- They measured calorie burn on their Fitbits and were also asked to record if they felt their performance was hindered by temperature-related discomfort.
- The average calorie burn was worked out across the group of 50 volunteers by adding up their total daily calorie burn and dividing it by 50.
