4 Reasons to Stop Stretching Before You Exercise

By now, you probably know how important it is to warm up before you work out. Warming up prepares your body for the increased demands of physical activity, reducing your risk of injury and complications. Beyond sending more oxygen and blood flow to your muscles, a proper warm up also prepares you mentally for what's to come—a workout that may take concentration, coordination and a little motivation.

The one thing you shouldn't do at this time is the very thing that most people do: stretch. So why is stretching before a workout a bad idea?

Here are four reasons why you shouldn't stretch before you exercise.
  1. Stretching is not the same thing as warming up. Confusing stretching with warming up is an all-too-common mistake, so don't feel bad if you thought the two were one in the same. You should spend a few minutes doing lighter intensity activity that mimics your upcoming workout—walking before running, slow cycling before biking, light aerobics before a fitness class. That is a warm-up. It gives your body time to adjust to the higher demands of exercise so that your breathing rate, circulation and heart rate can all increase in order to supply your working muscles with the blood, nutrients and oxygen they need to keep things running smoothly. Warming up also helps lubricate your joints. Stretching does not serve the same purposes and therefore does not pass for a warm-up.
  2. Stretching before a workout undermines your warm up. If you are going to stretch before a work out, you need to warm up first, and then stop moving in order to stretch. Have you ever thought about how the act of stopping to stretch cancels out the benefits of warming up? Your body temperature, heart rate, and breathing rate all drop considerably once you stop moving. After a few stretches, you're practically back to where you started: with cold muscles and a resting heart rate that is not ready to jump into a work out. This is one of the biggest reasons I do not advocate stretching after a warm up session. However, if you were to warm up, stretch, and then warm up again, that might be OK. But who has the time for all that?
  3. Stretching does not prevent injury. It wasn't long ago that fitness experts used to say that stretching would prevent injury. That's part of the reason people were encouraged to stretch before physical activity. But research has not been able to prove this theory. These days, it's generally accepted among fitness trainers, athletic trainers and physical therapists that the act of stretching does not prevent injury, no matter when you do it. According to a recent story by AP medical writer Maria Cheng, CDC experts who reviewed more than 100 stretching studies found that "people who stretched before exercise were no less likely to suffer injuries such as a pulled muscle, which the increased flexibility from stretching is supposed to prevent." So if you have been stretching before your workouts in an effort to prevent a sprain or strain, your efforts might be in vain.
  4. Stretching before exercise may actually increase your risk of injury. That's not just because it undermines your warm up. "Traditional stretches, like when people bend over to touch their toes or stretch their legs on a fence," wrote Cheng, "often cause the muscles to tighten rather than relax—exactly the opposite of what is needed for physical activity." Your risk of overstretching at this time is greater, and this tightness can undermine your speed and range of motion when you start exercising. Some research has shown that certain athletes who stretch are more susceptible to injuries and performance problems. Experts theorize that a certain amount of "tightness" is needed for muscle strength and power in certain sports, such as throwing a fastball or kicking a soccer ball.
This is not a campaign against stretching. I firmly believe that most people benefit greatly from stretching and don't do it enough. But it should be done at the right time and not pushed to the limits. Most research shows us that those who are most likely to suffer injuries are people on the opposite ends of the bell curve; the least flexible people—and the most flexible—are more prone to injuries and problems. That's good news for your average exerciser because you don't need to t urn into a human Gumby to stay injury-free. A normal range of flexibility, often called a "functional range of motion" can help decrease muscle tightness and keep yourself active, mobile and capable even as you age, when flexibility naturally takes a decline.

So when is the best time to stretch? (And yes, you should stretch!) If you haven't guessed it yet, it's at the end of your workout, right after your cool down. Your muscles and joints are much warmer and lubricated after a workout than they are before one (even if you warm up), which means you'll get more out of your stretches at this time. And because your body is returning to a relaxed state, stretching after exercise is simply a feel-good way to end your workout.

Overall, we should all aim to stretch regularly. It may take a little effort to change your habit of stretching before exercise, but the benefits and reduced risks are probably well worth it.

Do you prefer to stretch before or after your workout? Do you agree with these recommendations? Will you change your stretching routine after reading this?

    I"m just now learning this one. I'm seeing a PT and she has me doing a dynamic warm-up which is exactly what this article suggests. I wonder if my static stretching after my warmup (and before running) is what caused my knee issue to begin with! - 1/2/2018   5:36:02 PM
    I stretch after my workouts. I have read this one before. Thanks! - 11/25/2017   8:36:02 AM

    Since joining Sparkpeople almost a year ago, I've followed the instructions during and after Sparkpeople exercise videos and learned to warmup before exercise and stretch after cool down. So far no injuries and minimal soreness after sessions. Thanks for the great information. - 5/13/2017   11:22:34 PM

    A few minutes of easy stretches before a workout gives me a chance to focus on body awareness. The body awareness and focus is the most important part of my safe workout! - 5/13/2017   4:58:15 PM
    This article might do more harm than good for people that don't read it fully. The first point I don't see because you usually will stretch, warm up, and then workout. No cold muscles. Another thing I disagree on the value of stretching before a workout. People that are mostly inactive or aging need stretching before a workout greatly. - 5/13/2017   3:31:56 PM

    I never stretch before working out but I actually do like the way I feel when stretching after a workout - so everything you wrote here makes sense. - 5/13/2017   6:05:32 AM

    I never stretch after walking/jogging. I should start. I do stretch after doing cardio. I always thought it was weird to see people running then suddenly stop and start stretching. - 5/4/2017   11:53:08 PM

    Eh. I suppose it depends on what you're calling stretching - stopping and holding a stretch for 30 seconds for each muscle, versus a quickie 8-10 second stretch.

    I typically have a few stretches in the middle of my warm-ups. They're not held for long and they're certainly not held long enough for me to completely cool down. Generally this helps as I'm typically sore from my previous day's workout and some of my muscles may feel like they're cramping up during my warm-up. The quickie stretch loosens them up and then I'm good to go.

    And what about yoga? This exercise essentially is stretching and strength. Rarely have I ever encountered a class where everyone had to jog in place first before the class. You go right into poses. - 1/30/2017   3:16:57 PM

    I have always started my workout at a slower pace rather than stretching. If I stretch I get bored. I'm too impatient to waste time stretching. - 1/30/2017   1:35:29 PM

    I always warm up with light treadmill before working out, then stretch afterwards. It doesn't make much sense to me to stretch before working out. - 1/30/2017   12:15:01 PM

    Never had a stretching routine before exercising, lucky to have time to actually exercise, just start out slower and work your way up. - 1/30/2017   4:56:07 AM

    Bravo! Thank you for the "permission" to stop stretching before exercise. I followed the old way of thinking to stretch before( Yes, getting stretching confused with warming up) Only to find every time my motivation to exercise would be destroyed half way through stretching. I would grow bored and never make it or force myself to make it to exercise. Now exercise can be fun for me again! - 10/25/2016   11:59:17 PM

    For me, if I don't stretch before going for a walk (and I'm not talking about walking a 5K...I mean a nice mile or so on a regular day), my legs will burn and itch like there's no tomorrow. So, I do a little stretching before my walk and a little stretching after and I have never had any problems. - 10/25/2016   11:38:52 AM

    At every karate class I ever taught or attended (five different styles) we always stretched the muscles groups after exercising them (ie one set of push ups followed by a stretch and then another set of pushups).Trust me NOBODY had time to cool off there was not enough of a pause. - 7/18/2016   8:43:54 PM
    I watched a father and son the other day at the park. They had a soccer ball with them. The father stretched and stretched for at least 1/2 hour, very intense. The son, maybe 9-10 years old did some stretching although not as intense as the father. I figured they were going to play a soccer game with other people. After I completed my walk, maybe 1/2 hour, they were heading back to their car. So no game, just kicking the ball around. - 7/18/2016   8:08:45 PM

    I do not agree with this article and neither does my trainer. I have a shoulder injury and stretch before my warm up. If I didn't, I stand more risk of causing further injury to that shoulder than if I hadn't stretched. - 7/18/2016   1:10:06 PM
    Not sure I completely agree with this article. I do Martial Arts and find that if I do not stretch at all I have more issues. Of course I combine my stretching with warm up activities so maybe that is the difference. - 7/18/2016   11:13:25 AM

    I "warm up" for cardio by doing strength training first, and do enough stretching to pop my spine after. - 7/18/2016   10:05:43 AM

    I do know I can stretch much farther and get more out of it after a cool down...after a full workout. The warmer I am when I begin to stretch the better. - 4/22/2016   1:41:28 PM

    This is great information SP! Thank you. I used to stretch before and after a workout in the nineties and early 20's. Now I always stretch after my workout only (new research) because if I don't I'll be sore the next day after I get up guaranteed! I also have a few muscles on my back and neck that occasionally go into spasms the next day after working out without stretching and I can't move until I have taken ibupropen or Aleve. - 3/2/2016   12:01:44 PM

    I read in the book "Building Your Running Body" that the exception to this rule is that those who have been stretching before running all their lives should continue to do so, or risk injury. That has been my experience, so I continue to warm up and do light stretches prior to running. - 1/7/2016   2:36:02 PM
    I didn't know there was a difference between stretching and warming up. - 11/15/2015   2:59:32 PM

    I understand the dangers of stretching cold muscles. However, taking the time to loosen up before a workout I find really useful; I go running or do yoga after work, and a few minutes' stretching shoulders, legs, etc helps me spot and ease tightness in e.g. lower back etc. From experience, that cuts down on injury as it means I don't start off running in a desk-bound slumped posture. - 2/16/2015   5:34:58 AM

    Ditto. I start the day with at least 5-10 minutes of stretching in bed. After doing it, I feel much more ready to get out of it and do a real workout. I also have a sedentary job and try to take stretch breaks throughout the day. - 2/4/2015   4:14:20 PM

    Interesting blog. I agree it's best to stretch at the end of a workout, but I also try to stretch generally throughout the day, as I have to sit a lot throughout the day and get stiff. - 10/16/2014   10:09:33 PM

    I am certainly no expert, so I can't say that the recommendations given in this article are wrong or right. What I can say is that for me, working out doesn't go well if I don't stretch before (even if I do warm up).

    For me, stretching before the warm up loosens me up. It makes it easier for me to bend and move, and I feel better as I begin the warm-ups after I stretch. I also probably overdo it according to this article. I stretch before, during and after my workouts. However, I find that I rarely get sore (even after very intense workouts), I'm able to complete my workouts with more energy and my joints don't suffer in cold weather as much anymore. Yes, my heart rate goes down but I look at it like this: On the treadmill I gradually increase my incline and speed until I'm at that max I can take (5.0 incline and 3.4 mph). When I go straight through from start to finish without stopping to stretch, I don't burn as many calories. Why? Because I start to feel stiffer and stiffer the longer I go. Then I'm super sore and dead tired at the end so that I can't do anything else. I can barely drag myself upstairs to take a shower and I'm too stiff to stretch. When I take short breaks to hydrate and stretch, I can go for longer, I burn more calories and I'm energized at the end. Then I can go on to do my strength training, yoga and end stretching. I'm also energized (and not sore) for the rest of the day.

    That's a big difference for me, and I obviously know which one feels better. At the end of the day, the condition of my body and the calories burned are the most important things. When I stretch as I normally do (beginning, middle, end) I burn more calories and have more energy to complete the entire workout as well as energy for the rest of the day. When I don't stretch until after...I can barely stretch at all. I think stretching is something that varies for each person. Some people may be better served stretching only at the end while others may be better off stretching before and / or during. We must all do what feels best for our bodies. So I'll continue with my normal routine unless something starts to feel "off." I'll let my body tell me what's best. - 11/11/2013   9:10:05 PM

    Good article, I now know proper warming up is to mimic the activity I am about to do before exercise to get my body ready for an intense workout. I do still stretch in order to help out with my flexibility and general well being, however, I do it separately from my exercise sessions. I use it as part of my Yoga sessions~ - 6/22/2013   6:11:09 PM

    It's interesting that when I first registered on SP, stretching between the warm up and the workout was recommended.
    I never liked "interruptions" but did stretch to prevent injuries.
    My fiance always insists that I do it, too.
    I'm happy I can skip the "interruption" after the warm up tonight thanks to this blog post:) - 4/18/2013   4:42:58 AM
    I do treadmill before i will walk on it for 4 minutes and will run for 10 to 15 minutes and will do weights and elliptical,cycling,stepping.Will go home is this correct,even no difference in my weight will do this daily more than an hour - 4/18/2013   2:08:01 AM

    Learned a lot in the comments about static & dynamic stretches. I agree with those of you who are of the opinion that one's stretchin routine depends on the sport/activity in which one participating. Personally, I abhor stretching before working out (I'm a runner). I usually just start off with a light jog & that gets me going. When I strength train it's the same story, light cardio then I move into my strength routine for that day. Ironically, I love to stretch and I love yoga. I just rarely experience any particular benefit in sequentially combining stretch with my workouts. - 4/4/2013   5:34:10 PM

    As a former gymnast and dancer, I really am a huge fan of stretching. I'm 43 years old now and value my flexibility greatly. I can still do the splits on both sides and I can still put both legs behind my head.

    I'm one of those people that will allow a lot of time for stretching. There are times when I go to the gym and if I haven't worked out in awhile and my muscles are all cold and stiff, I will start by stretching. But I really pay attention to my body. I will spend about a half hour stretching and I will warm my body up through stretching. I feel like I get the blood back into my muscles by gently stretching and waking them back up again. My stretching is like a very slow dance.

    But even if I start my workout with a slow warm up stretch, I always end my workout with a stretch that is intended to work on my flexibility. After I am all warm from my work out, I want to really take my stretching to the limit.

    My new thing is stretching in the steam sauna. Some times I do this before my work out, some times I do it after. For me it is absolutely amazing.

    It really helps on the days that I feel resistant to exercising. I'll stretch in the steam sauna first, usually for about a half hour. I bring a 32 oz bottle of ice cold water in there with me too so I don't get dehydrated. Then after that, I am really warm and ready to work out.

    Or I will stretch in the steam sauna after my work out and I will do some really deep stretches slowly for about 30 minutes. The heat gets so deep in my muscles and I'm able to stretch deeper than if I were stretching outside the sauna.

    Being flexible really makes me feel really young. I still enjoy fun activities such as rollerblading, trapeze and aerial silks, and being flexible really helps with these activities.

    I want to still be able to do the splits at 90.
