When it comes to healthy habits, you can have too much of a good thing. Fiber is good for you, but too much fiber is a major diet no-no (if you've done it, you know what I'm talking about). Even too much sleep can backfire and hurt your health. And exercise is no exception.

In fact, trading evenings on the couch for marathon calorie-burning or muscle-pumping workouts day after day--without adequate rest--is a surefire way to burn out, hurt your performance and even get yourself injured. While everyone is different and no certain amount of exercise is automatically ''too much,'' it's recommended that you take one to two rest days a week, especially if you're working out at a really high intensity or with heavy weights. In general, exercising for up to 90 minutes (at a moderate intensity), most days of the week is reasonable and healthy, but you should take into account your fitness level, health status and how your body responds.

You might already be aware of some of the common signs of overtraining, but sometimes the body sends more subtle signs that you're working out too much.  These signs can sometimes be so sneaky that you may not realize your workouts are causing them.

We've gathered seven of the unique and misdiagnosed symptoms of overtraining. While none of these is guaranteed to be caused by overtraining (always talk to your doctor), it's possible that if you've been putting in lots of hours at the gym lately, your heavier workouts could be causing these less-than-healthy results.  

Exercise leaves you exhausted instead of energized.
Exercise should make you feel good and give you an energy boost. Yes, you might feel tired or fatigued right after a tough workout, but if you leave the gym exhausted, tired or generally feeling like you could go home and take a nap, it might be a sign that you're overdoing it. If you're not getting that feel-good endorphin rush that's one of the awesome by-products of being active, it's time to take a look at your training and see what your body may be telling you!

You get sick easily (or it takes forever to get over a cold).
When you exercise regularly, your body is constantly spending energy and working to repair those muscles. This means that when you come in contact with a bacteria or a virus, your immune system isn't able to give 100 percent to fighting off that cold or flu. So you get sick and can stay sick longer if you don't give your body the time off it needs to take care of itself. Remember, your body is an amazing machine that does much more than just power your workouts!

You have the blues.
Do the workouts you used to love feel more like a chore than anything else? Or do you generally feel down and unmotivated? It may seem counterintuitive since exercise has been shown to boost feel-good endorphins, but overtraining has been linked to a decrease in energy and mood. So if you have the blues, letting your muscles recover for a few days and getting really good sleep might be just what your body really needs. Of course, if you are severely depressed, see your doctor.

You're unable to sleep or you can't seem to get enough sleep.
How are you sleeping lately? Is your mind racing when your head hits the pillow? Are you unable to fall asleep no matter how many sheep you count or how tired you feel? Are you on the other end of spectrum where no matter how many hours of sleep you clock, you still feel tired? Both of these can be caused by overtraining. When you exercise too much, your body can interpret it as a stressor, sending out stress hormones like cortisol that can make going to sleep difficult. On the flip side, overtraining can actually make some people more tired than normal. Sleep is a time when the body and brain recovers, and if you're pushing it too hard, your body might be telling you that it needs more rest that you're giving it.

You have ''heavy'' legs.
You used to go out for a walk or a jog with a spring in your step! But these days? It seems as if your legs have been traded out for heavy lead; it takes a lot more effort to get going and stay going. Sound familiar? If so, overtraining may be wreaking havoc on your body. Heavy, tired and overly fatigued legs (or arms) can be caused by muscles that just haven't had enough time to fully recharge and repair.

You have a short fuse.
If the smallest things set you off or if you're feeling more irritable than normal, it could be due to over-exercising. When we're tired and worn down, it's far easier to let the little stuff get to us than it would if we were well rested. Think of exercise like spending too many hours at work on a big project for weeks at a time. Sometimes you just need a vacation and a break for some rest and relaxation!

You're regularly sore for days at a time.
We all know that muscle soreness is a good thing. It means that we've really challenged ourselves and that our bodies are working hard to make us stronger and fitter. But if you've been doing an activity or exercise for awhile but tend to get sore really easily--or stay sore for more than 48 hours--it's probably a sign that you overdid it and next extra rest. This is why it's so important to ease into exercise, adding time or intensity slowly over weeks instead of all at once. The body simply needs time to adapt and improve!

If you have any of these signs, it's probably worth cutting back on the intensity, frequency and/or duration of your workouts. Swap an hour run for 30 minutes of easy yoga or trade that high-intensity boot camp for a long walk with your dog. While it might seem like you're taking time off from your fitness and weight-loss goals, you're actually doing the opposite: You're making yourself stronger by giving your body the rest that it's (subtly) asking for!

    I use my waking pulse rate to detect over-traiining. When my waking pulse rate is higher than normal for a few days I cut back.
    One thing I always say is that you don't get stronger from working out, you get stronger recovering from your workout. When you don't give yourself time to recover than you are shortchanging yourself. - 4/23/2013 1:53:22 PM
  • My legs hurt really bad when I overdo it. - 4/14/2013 9:30:36 PM
  • Good article.I can relate.

    I'm new to SparkPeople and relatively new to regular strenuous exercise, Yesterday, I went to my Tai Chi class,. When I came home I felt seriously energized. My inner Tazmanian Devil surfaced. I went into a cleaning frenzy. In contrast, I went to a fun Mud Run/Obstacle course a couple of weekends ago. While I did great and finished the race, afterwards, I slept 16 hours. When I awakened I felt rejuvenated and refreshed. I guess I really needed the sleep.

    Thanks. - 4/3/2013 12:21:05 PM

    Great article and not something a lot of people are aware of! I remember training a few years back and constantly being sick, and injured every other month, on again off again training, as soon as my head hit the pillow I would fall asleep within seconds, it was not good! We need to remember to listen to our bodies!
    If you feel tired, try a warm up and see how you feel after that, maybe that day is better of spent going for a walk or taking a break. Training 6-7 days a week will actually take you further away from you goal in some cases, remember less is more! ~Mia St-Aubin - 4/2/2013 9:37:08 PM
  • Pretty sure I'm affected by all of these :\ - 4/2/2013 10:11:02 AM
  • I've felt the exhaustion after a good run and have definitely had the sore muscles for days but I just thought that was a part of the whole "no pain, no gain" philosophy. Having said all that though, I do not exercise everyday - five to six days a week - yes but not everyday. So I really don't think I'm over-exercising. - 2/25/2013 2:00:13 PM
  • I felt this way while doing the Insanity work out. I looked great but I was so crabby and sleepy.
    Thanks for the information.

  • This is an interesting article! I could see it easily turning into excuses. :)

    For me, I have a tendency to get really sick right when I get to what I think is a great fitness level. Right now I have bronchitis and it's a rather nasty case. The only cure is complete rest because it's self-perpetuating and the slightest strain inhibits recovery.

    I wonder if it became this bad because I continued exercising when I had a cold, if the cold was due to exhausting myself or due to the guy behind me who coughed through the whole workout session, or just bad luck.

    Someone else said there's a fine line between overtraining and not enough and it's really easy to find excuses not to exercise. - 11/29/2012 1:39:41 PM
  • I've felt the heavy legs and bored from over exercising. So true that rest can do the body good! - 11/29/2012 4:28:01 AM

    This is a great article sometimes I do feel the heavy legs. - 11/28/2012 1:37:13 PM
  • Fantastic article! I do high intensity training workouts and long runs six days per week and leave the extra day for yard work, gardening, mowing, washing the truck etc., burning anywhere from 5000-7000 calories per week. But lately, it has become a chore to remain motivated. The part of the article that refers to how you should feel AFTER you workout (energized, not completely spent), and the "Dead Legs" syndrome really spoke to me. Thanks so much. - 11/28/2012 9:42:37 AM
  • I relax if I'm sick, but I still have to work out every morning. For me, there's no such thing as "too much exercise." I shoot for three times a day and if people tell me they think that's excessive I ask whether they think eating three times a day is too much. It shuts them up. - 11/27/2012 3:17:32 PM
  • To avoid this, I take a week off of exercise ever 8-14 weeks, depending on how hard I am currently working out. - 11/27/2012 12:58:15 PM
  • it's a good article but kind of hard for me to read. a lot of these signs could also mean you aren't exercising enough (trouble sleeping, low energy). it's such a delicate balance! i live by the mantra "more is more" when i comes to exercising and harldy give myself a reason or excuse to miss out on exercise, maybe this article is trying to tell me something:) i have had really sore hamstrings since i last did strength training and i think that was 4 days ago. it's hard to understand though because when i used to work out with a trainer, he told me cardio was the best thing for sore muscles and to not skip a day after weight lifting. i def don't want to get injured though as if i couldn't work out, i'm pretty sure i'd get very depressed. good things to think about and pay attention to, i guess. - 11/27/2012 11:01:15 AM
  • Awesome advice! Lately I haven't felt as motivated to follow a strict training plan and feared it was burnout. Even though I pushed through that, I have noticed that I don't sleep as well at night which has never been a problem for me. Now I think I'll switch my aerobics DVD for some stationary bike time and extra dog walks... I feel motivated to keep some momentum rather than give up completely! Thanks, Sparkpeople for the encouragement! - 11/27/2012 7:25:16 AM
