As a fitness editor who has watched the “Electricity” music video dozens of times, I wanted to know more about (and try out) her workout routine. It’s clear that she makes her health a priority, but how does she stay in such great shape while touring? “I love doing something that’s really fast and quick, like a 15-minute HIIT session, which I can do before I start my day,” she said in an interview with Viva. “If I’ve got a really early call time, I don’t want to be waking up hours before I need to, to go and do a workout.” Albeit short in duration, Dua’s HIIT sessions make her feel grounded and ready for the day–which, given that we’re all about the mental health benefits of exercise, we can get behind. She even told Vogue a few of her go-to moves: jumping jacks, mountain climbers, and burpees. Being a ClassPass devotee, boxer, and runner, I was skeptical about how effective a 15-minute HIIT workout could really be. Could it leave me as stress-free as a long run or 60-minute class? I decided to give Dua’s workouts a try for a week. Here’s what happened. Here’s what they looked like: Circuit 1 (repeat 3x through) That said, getting a workout in every day was incredibly gratifying, both physically and mentally. I woke up each morning not dreading my workout because, like Dua said, it would be over before I knew it. And because I wasn’t doing something prohibitively intense that would leave me sore for days, I woke up feeling healed and energized, not sore and sluggish. In terms of the physical results, I did feel tighter and leaner but not wildly different. I find that whenever I start my day with a workout, I’m more likely to make healthier food choices that support my body, so that probably played a role in how I felt physically. In terms of the mental benefits, I started each day feeling accomplished and still energized, as opposed to some workouts that leave me feeling depleted. The one downside is that I didn’t find these shorter workouts to be quite as stress-relieving as more intense ones, but I feel noticeably better than I would have had I done nothing at all—which is a pretty incredible benefit to reap in just 15 minutes. I’m definitely going to work these circuits into my routine on days I don’t feel like trekking to a class, or maybe even while I’m on vacation. So if you’re wondering whether there’s a case for the 15-minute workout, and whether or not you should give it a try, consider the case closed. I say go for it!
