Runner’s World discusses interval training and factors to consider when planning for these workouts in the summer heat, according to experts including Polly de Mille RN, MA, RCEP, CSCS, USAT, exercise physiologist at HSS.

de Mille noted while it is warm outside, it is important to make time for a proper warm-up. “It may seem like you don’t need to and you may feel hot, but it’s important to increase circulation to muscles, ligaments, and tendons you’ll be stressing,” she explained, adding that even though the duration of your effort may be shorter than usual, it’s important to get up and out early in the day, or hold off until later in the evening to avoid the high heat.

Running may be the ideal social-distancing sport amid the COVID-19 global pandemic. And although you may feel like a pro at seeking out empty trails and roads now, if you’re bringing these intervals to a track, you’ll want to have a mask in tow. “Intervals with a mask on will not be so easy,” said de Mille. “I would definitely try to do these where you can be by yourself, and if that’s not an option, strategize as best as possible to be on the other side of a track from another running.”
