HIIT involves "short stints of exercise that keep your heart rate up with little rest in between each move, torching a ton of calories when you're short on time," says Jami Rogenski, personal trainer and HIIT group training instructor at Sweat Garage in Los Angeles. "You can knock out a 10-minute sweat session anywhere, without any equipment — just using your body weight, going at your own pace!"
Working out first thing in the morning means you head into the rest of the day feeling accomplished and hopefully a bit more energized. "I personally find that jump-starting my day with a HIIT workout increases my energy and restores mental clarity, setting an accomplished tone to the day bright and early," Rogenski says.
Want to try it for yourself? Here are four different HIIT workouts from Rogenski you can do in just 10 minutes at home (or in the park or gym or wherever you choose!) first thing in the morning — no equipment needed.
All four workouts are simple, straightforward and effective, but not so intense or exhausting that you won't have energy left for the rest of the day. Don't forget to warm up before your workout and cool down afterward!
