Expert Solutions: Cardio or Strength Training First?

A Discussion with SparkPeople's Fitness Experts

When it comes to weight loss, I recommend doing cardio first. Cardio exercise is going to help you burn the most calories in the shortest period of time. Although weight training is also going to help with weight loss (and should be part of any workout routine), I would make cardio the activity you're going to do while you have the most energy and your muscles are rested. No matter which order you choose, the second activity is going to suffer (to a certain extent) because you've already used up some of your energy. If you can do your cardio and strength training on different days, that would be the ideal situation. But no matter which order you use, you'll want to do a good 5-10 minute warm up before each workout session.

What I always say matters most is that you're actually doing both cardio and strength training—in any order, on any days, at any time—and continuing to push a little harder to become even more fit. While I do agree with the perspective that it’s ideal to do cardio and strength training on separate days for optimal results, most people’s schedules don’t allow that. If you have to do both in one day, your second best option is to do them at different times of day—such as cardio in the morning and strength training in the afternoon or evening. This two-a-day approach gives you time to rest and refuel enough that you’ll have optimal energy once again by the time you get to your second workout.

But exercising twice in one day isn’t feasible for most busy people. If you have to fit in both during one workout, you should focus on whichever exercises will help you reach your main goals, and do those first. Perform cardio first if you want to lose weight, train for an endurance event, or achieve the general health benefits of exercise. Do strength first if you want to build size and power. Be sure to eat something within two hours of starting your workout session and within about one hour of completing it. Keep the length of your combination session reasonable and realistic so that you have enough energy for each part of your workout.

Personally, I do a little bit of everything—cardio first on some days, strength training first on others, cardio and strength on separate days, and even two separate workouts in one day. I like the variety, but also enjoy the mental and physical break that comes when I can focus on just one thing at a time. Changing the timing and order of your exercise program is yet another way to keep your body surprised, stave off boredom, and maximize your results.

  • I have to get my strength training in first, otherwise I won't do it. - 9/26/2015 9:30:35 AM
  • I do about 5 min on the exercise bike to get my heart rate up before I lift wts. - 6/9/2013 11:01:05 AM
  • I agree with all of the trainers, but what Nicole said sounds the most like my philosophy.

    The most important thing is that you do both, regardless of the order or time of day. If you were doing nothing before and you are doing something now, it really doesn't matter what order you do that something in. The important part is that you are DOING it! - 6/9/2013 10:46:47 AM
  • You would not normally want to flush that away with cardiovascular exercise. - 10/23/2012 12:40:48 PM
  • Yes, better to do them on different days. Yes, better to split them up with hours in between if needing to do them on the same day.
    If you must do them back to back, it is almost always better to do the resistance training last. If you are trying to lose weight, it is better to do the resistance last. If you are trying to build muscle, it is better to do the resistance last.
    The best way to lose weight over the long run is to increase your metabolism day in and day out; this means more lean muscle. Protein as explain in the beginning of the article is a factor; yes you should eat some good protein just after the workout. Beyond that, the pump you should be getting in the resistance workout is key to building the muscle. The swelling (so to speak) of the fibers. You would no normally want to flush that away with cardiovascular exercise. - 10/23/2012 12:37:32 PM
  • For the poll, I had to check the "do it in same day, different times of day" even tho I use the 30 Day Shred circuit training DVD, which alternates between the two! There's no option for circuit training.

    I do need to fit in some elliptical, tho, to increase my endurance and add to calories burned off. I had a lower body injury over the summer that prevented me from doing anything much like that. It's now feeling 98% better. In which case, I'll be alternating it, I think, or doing it later in the evening, after dinner. - 10/19/2012 2:35:33 PM
  • I was going to ask a similar question - what about interval training with both strength and cardio interspersed throughout a one-hour workout? Some of the most popular exercise videos are organized in this way... - 10/19/2012 11:16:09 AM
    In a gym It much better for me to do strength training first because cardio first means I leave a puddle of sweat at each strength machine. Also cardio leaves me too tired to do the Nautilis-like machines. - 10/19/2012 10:54:44 AM

    I've always had trainers tell me you should always do strength training first, primarily for safety reasons. Having proper form is very important when doing strength training, both in terms of maximizing the efficiency of your workout and in terms of preventing injury. You are far less likely to have good form when you are tired after a cardio workout. Much better to workout with weights first then do your cardio. - 10/19/2012 9:39:08 AM
  • I keep hearing that is actually strength training that makes a difference in weight loss for the long haul??

    So, yes, I'm still somewhat confused. I want to lose weight.

    Should I just do cardio with a bit of weights added in?
    OR do I focus on weights 3 x's a wk & fill in w/ cardio? - 12/15/2010 7:35:59 PM
  • Interesting topic and thoughtful suggestions...I thought the article was going to talk about when beginning an exercise program if people should focus on cardio or strength training to lose weight (think of the time in the gym on biggest loser).
    My personal trainer used to always require that I do a minimum of 10 minutes cardio warm up before weight training, and I was often pretty bushed afterward, although I would try to do maybe 30 minutes on the treadmill.
    I need to resume strength training, so I will keep these suggestions in mind and probably split the workouts instead of trying to do everything in one session. Just as when I cycle, I find I have to fuel up beforehand, or I will run out of energy. - 10/1/2010 1:34:50 AM
  • I've always done cardio first - I'm not sure why, but that's the way I've always done it LOL. If I thought I would actually get my butt back to the gym a second time in a day, I think I would like to do two separate sessions, as suggested by the article. But I'm not ready for that yet so I'll settle for managing to get once a day in LOL. - 2/22/2010 12:47:20 AM
    Sometimes I separate cardio & strength on alternate days. And it's true that I see and feel the best results doing this. But most often, because of my schedule, I do both on the same day, starting with cardio, or I do a circuit workout which combines both.

    I don't think I have it in me to work out twice a day. Once is plenty. LOL. - 10/11/2009 10:52:32 AM
    I didn't even know there was a question about which type of exercise to do first. I've been doing a circuit training routine so far, but when I'm able to get in more fat burning I guess I'll go for cardio first. - 10/11/2009 2:40:40 AM
  • Answers a lot of my questions...I've been doing things backwards! - 5/8/2009 9:26:51 AM
