Point blank: You’re busy and it’s hard to get to the gym sometimes — OK, a lot of times. I’ve been there, even as a personal trainer and someone who actually enjoys exercising. Working out can often seem like an extra bullet on the never-ending to-do list, nagging at you as more of a chore than anything.

There are a lot of ways you can make exercise more attainable, such as making it fun or enlisting an accountability buddy, but when time is the issue, the best thing you can do is to just work out less.   

Contrary to popular belief, you don’t need to spend hours upon hours in the gym or on the road to see fitness gains. To reap the many health benefits of exercise, you just need to get your heart rate up for a bit and focus on strengthening the major muscles — and you can do all of that in 20 minutes or less.

Benefits of short workouts

Remember with the high-intensity interval training craze started in the mid-2010s? Trainers and exercisers everywhere started evangelizing the benefits of short, intense, interval-based workouts, and it turns out that all the preaching is based on solid science: HIIT has been proven more effective than steady-state aerobic exercise (like jogging) time and time again. HIIT may also be more effective than weight training alone, at the very least from a time standpoint.

Even exercise “snacks” — bursts of activity as short as 20 seconds — can seriously improve your fitness when done a few times each day

This is largely because HIIT challenges both your cardiorespiratory fitness and your musculoskeletal fitness, bringing about improvements to your heart, lungs, muscles, nervous system and pretty much everything else

Of course, the ideal is a balanced workout regimen that combines steady-state aerobic exercise, interval training and resistance training over the course of a week, but this article isn’t for people who have time to do all that.

How to get the most out of short workouts 

When it comes to short workouts, you want to focus on intensity over all else (except good form, of course). 

The following elements make for effective short workouts: 

  • Compound movements that utilize more than one muscle group, such as push-ups and squats
  • Explosive movements that require power, such as tuck jumps and long jumps (also known as plyometric movements)
  • Full-body movements that tax your cardiovascular system, such as burpees and mountain climbers

4 workouts you can do in 20 minutes or less

Now that you know all about the benefits of short, intense workouts, it’s time to put that knowledge into sweaty action — below are five workouts you can do in less time than it takes to eat lunch. For the sake of simplicity, I designed all of these workouts as bodyweight-only sessions you can do anywhere.

Oh, and before you start: Don’t skimp on your warm-up and make sure you pump up the tunes for a better burn

Workout 1: Lower body

Complete the following for time (as fast as possible):

  • 50 air squats
  • 20 jump squats
  • 50 alternating lunges
  • 20 alternating jump lunges

Give yourself a time cap to make it more challenging.

One key to a good workout, intense or not, is good form. You’ll reduce your risk of injury and improve the effectiveness of your workout.
