As we enter the New Year, many of us decide to set new targets in the form of resolutions. Following the festive period, diet culture puts a lot of pressure on us to “shed the holiday weight,” but this is unfair. You still deserve to eat well and fuel your body even if you went hard on the mince pies last month. If, however, you’re keen to move your body more in 2021, a new study published in the Journal of Applied Physiology has discovered an interesting link between exercise and temperature. The research, which looked at High-Intensity Interval Exercise (HIIE) in the cold, marks the first time the immediate and long-term effects of this type of exercise have been scientifically investigated.
