Life is pretty busy. It can be hard to find time to sleep at night, let alone get in some daily exercise. Finding a fitness regimen that fits your life doesn’t have to be impossible, even when time is tight.

Adults should get at least 150 minutes of moderate-intensity aerobic activity every week, along with strength training, according to the Centers for Disease Control and Prevention. But finding big chunks of time to work out can be near impossible for some.

Fortunately, you don’t need to sweat it out for an hour to reap the benefits of exercise. When crafted correctly, a 20-minute, 15-minute, or even 10-minute workout can get you burning calories and achieving your health goals. We rounded up the best, short workouts on the web and think there’s something for everyone here. On the days you have a little more time, consider stacking these workouts to get a full-length session in.

‘10 Minute Home HIIT Workout’

As a warmup you're basically trying to get some warmth in your body, lubrication around your joints, and acclimatize to the intensity of the workout. So just start with basic moves, lots of which are in this video — squats, lunges, pressups — then increase to burpees until your heart rate has increased.
– The Lean Machines

This 10-minute session with The Lean Machines is far from a walk in the park. Because it’s high-intensity intervals, you’ll definitely get your heart racing and your muscles heated up. The focus of this session is calorie burning, so get ready for a challenge.

‘12 Minute Kickboxing Cardio Fat Blast Workout’

Tiffany Blair hosts this video from Psychetruth. It’s a kickboxing workout that focuses solely on the lower body, so get ready to tone your thighs and glutes. The moves aren’t necessarily fast, but you’ll definitely get your heart racing.

’12-Minute Fat-Burning Cardio Core Bodyweight Workout’

If you're a beginner and just starting out with a training program, it's always a good idea to check with your doctor to see what's right for you. That being said, it's very beneficial to be active for at least 30 minutes per day and that may include walking, biking, hiking, jogging, weightlifting, or whichever other activities and sports you enjoy doing. Everyone's fitness journey is unique so get out there and find yours!

This video comes from Fit Bottomed Girls and is hosted by the “Fit Bottomed Dude,” Sean Vigue. It focuses on core strength, which plays a role in so much of what we do on a daily basis. All you need is a yoga mat and 12 minutes to tone your core and burn some fat.

‘15-Minute Bootcamp Workout’

If you’ve got 15 minutes, plus a few extra to towel off, you can get this heart-thumping workout in! Hosted by Anna Renderer for PopSugar Fitness, it was inspired by the show “Pretty.

‘Get Thinner Thighs’

This workout is really for anyone who wants to strengthen their inner thighs and work on the thigh gap. It is going to tone the leg muscles so you have more definition! It is a killer and it might look easy but everyone will be feeling the burn after!
– Rebecca-Louise

If your thighs are a trouble spot, you’ll love this video from Rebecca-Louise. The workout is filled with lunge varieties, so you’ll feel this all throughout your quads, hamstrings, and glutes. The sea backdrop is a great distraction when your muscles are screaming for a break.

‘15 Minute HIIT Interval Workout: Body Weight’

Melissa Bender hosts this quick high-intensity interval workout. The great thing about HIIT is that it doesn’t take long to fit in an effective workout. You’ll do a session of hard work followed by a period of recovery, and repeat multiple times. As Bender says in the video, adjust the interval lengths to fit your abilities.

‘17 Minute No Equipment Total Body Circuit Workout’

I recommend people get active every day — but balance their workout routine with three to four nonconsecutive days of strength training, two to four days of cardio, plus one to three days of flexibility or stress relief.
