If you work out regularly, you’ve undoubtedly heard the buzz surrounding high-intensity interval training. HIIT mixes intense bursts of exercise with rest periods, burning more calories in less time than other forms of cardio. It’s long been considered one of the most effective workouts for weight loss for that very reason. What’s more, you don’t need a ton of space or fancy equipment to do it.
“It’s possible with a stretch of space no greater than your arm span to get an amazing full-body workout that will leave you feeling like you tackled every piece of equipment at your gym,” Karisa Curtis, an NASM-certified personal trainer in Los Angeles, told POPSUGAR. “To achieve that, intensity is key – so a HIIT workout is your best bet to get a great cardio workout, torch calories, build endurance, and burn fat without all the space or equipment.” Whether you’re working out in your dorm, a small apartment, or a hotel room, Karisa’s intense, 45-minute routine is exactly what you need to get started.
45-Minute, At-Home HIIT Workout
Equipment:
- Mini band
- Light to moderate set of weights (three to eight pounds)
Directions: This 45-minute workout is broken down into four segments: a 10-minute warmup, a 24-minute HIIT circuit, a three-minute, high-intensity finisher, and a five- to 10-minute cooldown. For the circuit, perform each of the six exercises for 40 seconds, resting for 20 seconds in between, and repeat that for a total of four rounds. Things are going to get sweaty, so make sure you have a towel on hand.

Warmup
HIIT workouts are high exertion, Karisa explained. Get your body prepped with a dynamic warmup to slowly raise your heart rate, loosen up your joints, and increase blood flow to the muscles. For this warmup, you’ll do each exercise for 30 seconds, resting for 10 seconds in between. Repeat the circuit three times, for a total of 10 minutes.

Cooldown
A cooldown is especially important after a workout as strenuous as HIIT to safely slow the heart rate, reduce muscle soreness, and maintain flexibility, Karisa told POPSUGAR.
Take five to 10 minutes to do some lower-intensity movements, such as lateral lunges and Cat-Cows, as well as some static stretches, holding each for at least 30 seconds to properly recover from your efforts. Some good moves include a standing quad stretch, crossbody shoulder stretches, and seated forward bends – find a more comprehensive list of stretches here.
