Seriously, should you do cardio before or after weights?

Why You Should Do Cardio and Weight Training

Whatever your fitness goals, odds are the solution is some combination of resistance training and conditioning.

If you want to keep it superficial, you could look at it this way: Strength training builds the muscle that gives you a pleasing outline when you are wearing your one-size-too-small shirt, and cardio helps burn fat to give you definition for when you take the shirt off. 

Way more importantly, both resistance training and conditioning are significant in general bodily health. Lifting weights increases bone density1 as well as muscle mass (two things we lose as we age). Strength training also serves as a natural way to promote positive hormone balance2 without the “supplements” (WINK).

Cardio has significant benefits as well. The American Heart Association states 150 minutes of moderate-intensity aerobic3 activity promotes positive heart health. With heart disease still the number one cause of death in America, hitting the treadmill a few times for the amount of time a Friends rerun takes to play on TV isn’t a lot to ask.

Cardio: Before or After Lifting Weights?

So when should you do cardio? That truly depends on your goals. In most cases, we lift before we breathe hard. But, there are exceptions:

Goal: Lift Heavy

If you want to squat/clean/deadlift heavy weight, then everything you do before your top sets needs to be focused on one thing; priming your body for the work it needs to do. Possible uses of “cardio” as potentiation or pre-fatigue aside, tiring out your muscles (and your mind) before a big lift can increase your risk of injury. 

Exhausting yourself before lifting weight4 will likely reduce your ability to produce force, and may or may not have a systemic effect on strength5 over the course of a training block.

That being said, you might just be out of shape. If you get out of breath after a 10-minute warm-up walking on a slight incline, it’s time to put down the triple McRib stack and get in better condition.

Goal: Run a Race

In this situation, cardio is the goal, so cardio should be the priority. Runners should absolutely cross-train, either separate from a run or potentially after one, depending on your time constraints. Generally, people with a road race in mind aren’t trying to also squat 500 pounds, so doing lighter resistance training after a run is perfectly acceptable.

Goal: Lose Weight

If weight loss is the goal, your body will actually burn more calories if you do your cardio workout after you hit the weights. This is due to the magic of post-exercise oxygen consumption. Basically, that wicked pump you got on the hack squat puts your body into a deficit it needs to recover from. This makes the body have to work harder at everything else it needs to do afterwards, which burns more calories.

Goal: Do the Work

There is another branch of science relevant to our conversation; psychology. Let’s face it, it’s stupid easy to blow off cardio after a hard workout session of squats, good mornings, and deadlifts. 

If you were really good at it, you might have warmed-up just a little bit longer than you had to, and rested between sets just a little bit more than you should have. Maybe you also walked to the water fountain way across the gym instead of the one right near your gym bag. 

When you finished it was almost plausible that you didn’t have time to get your cardio exercise done. Well done.

Sticking cardio at the front of your workout may not be the most efficient way to burn calories, and it may mean you can’t lift as much weight, but if it means you will actually DO the cardio, it means more fat burning than not doing it at all. If you are intelligent with the type of exercise you choose, the extra blood flow may not even be a bad thing. 

Pulling your shirt up to look at your abs in the mirror doesn’t count as blood flow.

Goal: Save Time

One more option is actually combining your cardio with your strength workout. Doing bodyweight/barbell/dumbbell/kettlebell circuits is both incredibly taxing on your cardiovascular system, and a great way to help build muscle in most trainees. You can even set up separate upper-body and lower-body circuits if you want to focus more on that.

Another way to combine weight training with some added cardiovascular exercise is to stick low-intensity to moderate-intensity cardio into the rest periods between sets of compound movements. Using the Ski-Erg in between sets of bench press feels great, as does jumping rope or doing kettlebell swings in between squatting or other lower-body movements. As long as you have a logical lifting program, and you lower your weights accordingly to account for the accumulated fatigue, this is an incredibly time-effective option.

Which Type of Cardio Is Right for Your Strength Training?

If you puke in the squat rack, you probably shouldn’t also puke on the track. If you want to pass out in the grass, maybe don’t pass out deadlifting heavy weights. 

Do you get what I’m saying? Layering intensities is important to avoid injury and burnout; not every part of every workout needs to be the most intense thing you’ve ever done.

High-intensity activities like lifting heavy weights exact a heavy toll on the body’s system. Repeat bouts of explosive movements tap into the body’s glycogen reserves. Alternatively, moderate-intensity cardio doesn’t hit this energy source as the body stays in the aerobic zone (long story made short bro science: aerobic = with oxygen, anaerobic = without oxygen).

Therefore, if you are really focused on strength training, then lower-intensity cardio (like a brisk walk or steady-state row) would be ideal.

However, if you are short on time and have other goals, then HIIT may be a more time-efficient tool for fat loss6 than steady-state cardio, partly because it can mimic some of the same kinds of anaerobic effects as resistance training. Many warm-up protocols leverage this similarity and resemble truncated versions of full-body HIIT workouts.

Therefore, you could prioritize lifting weights and then hit a short, high-intensity workout afterward to reap some of the cardio benefits. 

Much like a Nirvana song, you need to pick when to go hard and when to mellow out. You probably don’t see too many bodybuilders doing burpees, nor do you see many marathon runners doing max effort farmer’s carries. Somewhere in the middle, CrossFitters are happy doing a little bit of everything.

How Often Should You Train?

Low-intensity, steady-state work (think walking your dog or mowing a large lawn) can, and probably should, be done every day. You can use a treadmill or an elliptical if you don’t have a dog or a lawn. Articles on The 5 Best Ways to Get Shredded With Dog Walking will be all over the internet soon, so be a cool kid and get ahead of it.

Professional athletes can train 3 times a day all week. If training isn’t your entire life, and you have petty annoyances like a job, family, cats, and a healthy desire to enjoy your precious, limited existence on this earth, you can do what everyone else does and lift weights 3-4 times a week. 

RELATED: How Much HIIT Should You Do?

The American Heart Association recommends 150 minutes of moderate-intensity or 75 minutes of high-intensity work each week. The organization also says you should do resistance training at least twice a week.

Stop going to the gym just to use the elliptical. Make it a habit to do some sort of resistance training every time you work out. You don’t have to have some crazy Enigma machine matrix to hit each muscle group X times a week and Y times a month. Just try to fit in some kind of squat, hinge, push, pull, and carry every week. If it was rocket science the dude who used to cheat off you in high school wouldn’t be bigger than you.

If that feels too overwhelming, consult a personal trainer for help setting up a lifting program.

Cardio Before or After Weights: Q&A

Is it better to do cardio before or after workout?

In a vacuum, personal trainers usually say cardio is better after lifting, but it depends on your goals and specific modalities. You almost never want to attempt a maximal lift in a severely fatigued state. If you postpone your conditioning workout until after you have lifted weights, you may fatigue faster (but this isn’t a bad thing!). Due to post-exercise oxygen consumption, lower intensity activities will  burn a larger amount of calories for up to 48 hours after your heavy weight training session. Increased muscle mass also contributes to a greater number of calories being burned6 even while at rest. This creates more “free” opportunities for fat loss.

This isn’t at all to say that weight lifting doesn’t tax your cardiovascular system! If you’ve ever pushed reps on the front squat to 10, 15, or 20, you know your heart and lungs will feel like they are going to explode before your legs give out. Consider what function cardio plays in your fitness goals; are you using it as a calorie burning tool, an athletic development tool, or a heart health tool?

Also remember that a 10 minute warm-up isn’t cardio. Don’t be afraid to sweat and peel off a layer of clothing before getting to your serious lifting. Your gainz will thank you.

Should I do cardio before or after weights to gain muscle?

Who says you should be doing cardio at all if you want to gain muscle? Building muscle mass in a caloric surplus is insanely easier than trying to manipulate macros to build muscle and lose fat. If you are a beginner, you can get away with these types of “newbie gains,” but it’s not sustainable. What’s one way of making sure you stay in a caloric surplus? Lower the amount of physical activity.You can’t do everything all the time if you want to make significant changes to your body.

If you still feel like you absolutely need more aerobic exercise in your life, do it after you lift or on “off” days.  Think of a cardio session as an opportunity to flush blood through your muscles, rather than a chance to make your lungs burn.  Try to maintain, not improve. You are already asking your body to get bigger, don’t confuse it by telling it to get smaller.
 If you gain muscle mass your body fat percentage will actually go down without losing any weight. Math!

Is it better to run before or after lifting?

Some people like to run to get warmed up, but if you are training full body lifts like the snatch or the bench press, there are probably better options. If your workout routine includes running long distance, it may be wise to do it after you lift, or even on a totally separate day.
If by “lifting weights” you mean twirling a body bar in a dance studio or doing light dumbbell complexes, there is nothing wrong with running beforehand.
