"Ma'am, step away from the treadmill!" - 4 Indications you're doing too much cardio

Sometimes when I go to the gym, I have this urge to tell some of the most religious treadmill riders "Ma'am, Step away from the treadmill!" No matter how many articles and reports are written on the benefits of exercise other than cardio, it never ceases to amaze me how many women (and men too...) relegate themselves to the endless monotony of the treadmill - or for that matter, any other piece of cardio equipment.  Moreover, these individuals will do cardio for over an hour...sometimes hopping from one piece of cardio equipment to another...never even considering time in the weight room, in classes or outdoors.

Although there are definite benefits to doing aerobic exercise; strength, core and flexibility training all provide numerous health benefits that cardio can't:  They increase muscular and bone strength, increase lean body mass, safeguard against injury and boost metabolism while decreasing fat.

Is it possible you are overdoing the cardio?  Here's how to know:

  1. Time: Unless you are training for a race, marathon or triathlon, there is no need to do more than 30 minutes of cardio (with your heart rate between 65% - 85% of your maximum heart rate) when you workout. Fitness Revamp: If you want to exercise for over 30 minutes, you are better off doing a 20 - 30 minute cardio session and another 20 - 30 minutes dedicated to strength training, stretching and/or core training.
  2. You aren't seeing results: If you are trying to lose weight, yet you aren't seeing results, it may be because of too much cardio.  Believe it or not the idea of 'burning off fat' does not stem from cardio...it stems from strength training.   Fitness Revamp: Build in 20 - 30 minute strength training sessions 2 - 3 times a week.
  3. Injuries: Too much wear and tear on your muscles and joints can end up in an injury...or even worse, multiple injuries.  Incorporating flexibility and strength training helps to strengthen the joints which will prevent pain and damage to joints. Fitness Revamp: Take the time to stretch before and after your cardio sessions.
  4. Boredom: Does it take a lot to motivate yourself to go to the gym?  Doing the same type of exercise every day, of every week, of every year is...BORING!  Working out should be fun and should make you feel good.  Fitness Revamp: Mix it up.  Take a class or two that interest you each week.  Get into the weight room and do a few sets of bicep curls.  Go hiking.  Do things that motivate you and keep you interested.  Being active is what is most important...not the time and mileage on a piece of equipment.

Do you think you are overdoing cardio?  Have you found any of the above indicators true?

    I admit, I'm one of the people who does WAY too much cardio. I do 60 minutes of cardio each day on various machines, plus 30 minutes of weights three times a week. On the days I don't lift, I do 90 minutes of cardio. I usually help out my trainer teach his kickboxing class for extra workouts on top of all of it, too.

    For me, it's mental-everytime I try to back off the cardio, I beat myself up about it. I am a recovering anorexic, and while I've straightened out my eating habits, all of my cardio is how I give myself "permission" to eat. I do everything else though-I'm very flexible and I take time to stretch, and try to get outside to run or hike on the weekends so I'm just just staring at the same wall on the same treadmill. I'm rarely injured or bored, and I take supplements recommended by my trainer and doctor to keep healthy.

    Everything you've said here Brett is absolultely correct though, especially if you don't lift weights. The cardio queens who don't lift always look soft and um, "loose," due to their lack of tone. Someday I'll figure out how to exercise less obsessively, and if nothing else, I've learned over the years that cardio alone is not good enough-you definitely need weights!

    Sorry but weightlifting doesn't "burn fat." Having more muscle does stimulate the metabolism in the sense that it takes more calories to support a pound of muscle at rest than it does to support a pound of fat at rest, but muscle doesn't "burn fat." Additionally, doing more tan 30 minutes of cardio doesn't carry ANY more risk of injury than strength training does. In fact, studies have shown that running (for example) actually helps strengthen the knees and joints. Stop judging others while you're at the gym, and focus whatever it is that YOU like to do.

    To think that some people are obsessed with exercise yet other people don't exercise enough. Besides, if we walk, does that count? Either way, that means that PE is a waste of time. Do you think I could show the principal this article and persuade him that PE is pointless?

    Alison, I'm not sure how old you are, but PE is part of a curriculum for a reason. It instills the importance of activity in your life. Further, many people in PE class are often not exercising at full intensity. This article is geared towards people who are exercising at high intensity, on cardio machines for long periods of time...and most likely, are not doing anything else but cardio. I have to believe this is not the case in gym class.

    Jackie D-actually, weightlifting burns a lot of fat. I burn more fat and calories lifting weights that I do when I run, simply because my body is accustomed to running. Weightlifting is harder for me, and my heart rate skyrockets when I do squats, but barely elevates if I run for 30 minutes at 7.5 mph. All cardio is better than nothing, of course, but weightlifting is just as important.

    Funny reactions here. Well, whether cardio for more than thirty minutes is helpful to everyone or not isn't the issue. If it works for you then keep doing. If it doesn't, then mix it up. I like it when I get more than thirty minutes in. I feel better, and it is so good for destressing.
