Should You Do Cardio Before Strength Training?

If you want to lose weight with exercise, the exercise guidelines set out by the American Council on Sports Medicine recommend up to or more than eleven workouts a week.

That's five cardio workouts, three strength training workouts, and three flexibility workouts and that number could change depending on the intensity of your workouts.

The harder you work, as in high intensity interval training (HIIT), the shorter the workouts.

But if you're doing lower intensity workouts, you may need to workout up to 7 days to see significant weight loss results.

Trying to cram that many workouts into one week often feels impossible, and, for many of us, it seems like the only way to do that is to combine workouts.

That leads to the age-old question: Which do you do first, cardio or strength?

The answer isn't always cut and dried but here's one way to look at it: If your goal is to lose weight and you want to maximize your workouts, doing cardio first might be the way to go.

The Benefits of Cardio Before Strength Training

If you're confused about whether to do cardio or strength training first, you're not alone. Experts differ on this issue, with some recommending cardio beforehand to get your body warmed up for lifting weights.

Others suggest the opposite, saying that cardio may fatigue your muscles, thus making your weight training session less effective.

So, who's right? There really is no right answer and what you ultimately do will be based on your goals.

However, if your goal is to lose weight, cardio before strength may be your best bet because it:

  • Maximizes Your Calorie Burn - Doing cardio and strength during the same workout not only helps you burn more calories but doing cardio first actually maximizes the calorie expenditure of your workout since a session of cardio typically burns more calories than a session of strength training.
  • Increases Your Afterburn - Doing cardio first maximizes your post-exercise oxygen consumption (EPOC), or the number of calories your body continues to burn after your workout. One study published in the Journal of Strength and Conditioning Research followed 10 males who completed three different workouts:
    • A weight training workout
    • A weight training/running workout
    • A running/weight training workout.
    The findings? The afterburn was greatest after the running/weight training workout. They also found that running was harder for the body after lifting weights first, which makes sense, particularly if you target the legs. Obviously, the lower body is heavily involved in running so it makes sense that your legs might be more fatigued if you lift first.

And what about building muscle? Will doing cardio first negatively affect your body's ability to gain strength and endurance? One study, which followed participants over a three-month period, found that doing cardio during the same session as strength training didn't change the development of muscular strength, explosive strength and power.

The real key is to go by your goals. If your main goal is to build bigger muscles, lifting weights should always come first so you can give all your strength and energy towards that goal.

You may not even want to have much cardio, or stick with shorter HIIT cardio workouts to increase your power and endurance.

Make It Work For You

It's nice to have guidance but how you schedule your workouts will depend on:

  • Your goals: If your goal is overall weight loss, you might do cardio first to maximize your workout time. If you have a specific goal or sport, you'll want to put that first. For example, if you're training for a marathon, you'll want to focus your best energy on your running workouts and schedule your strength workouts for your off days.
  • Your preferences: If lifting weights first feels good to you, there's no reason you have to change that. The idea is to have a consistent, balanced workout routine in whatever format fits your life.
  • Your schedule: In an ideal world, you'd be able to do separate strength and cardio sessions, but most of us don't have that kind of time. Carve out time to exercise and fit what you can into that time.

Fitting It All In

With all this in mind, how do you fit it all in? What does a typical workout schedule look like if you're combining cardio and strength?

There are so many ways to set up a cardio/strength routine, there's no way to cover them all. However, below you'll find some examples:

Sample Cardio/Strength Weekly Workout Calendar

Day 1:  30-Minute Cardio Medley WorkoutUpper Body TrainingDay 2: Choose 1 Workout from Burn 300 Calories in 30 MinutesCore Training
Day 330-Minute Low Impact Cardio Blast Workout (2 circuits), Lower bodyDay 4: Rest
Day 5: Cardio Endurance Workout, stretch  Day 6: Total Body Home Strength or Circuit Training
Day 7: Light 20-30 minute walking workout 

It may take time to figure out a schedule that works for you and that schedule may change from week to week, depending on what's going on in your life.

The key is to keep things simple and fit in what you can. There's no rulebook and there really is no wrong way to exercise. Just making sure you do something every day is a great goal to have.
