Overtraining is defined by Wikipedia as a “physical, behavioral, and emotional condition that occurs when the volume and intensity of an individual’s exercise exceeds their recovery capacity. The term is defined differently depending on where you look, however. Overtraining basically amounts to is working harder than the body can keep up with. If your body can’t recover from workouts you will eventually hurt your progress or injure yourself. Because P90X is a tough workout program, we have heard that some are concerned if P90X and overtraining go hand in hand. The short answer: no.

Overtraining is much more than working out hard. Elite athletes workout consistently day in and day out and seldom, when trained properly, do they suffer from overtraining. The intensity of your workout doesn’t always increase your chances of overtraining. P90X and overtraining is not any more common than overtraining from running, in that regard.

The key to preventing overtraining in any fitness program is listening to your body and resting when appropriate. Every good training program should have easy days or rest days built in. P90X does this with occasional days off. For some people, believe it or not, rest days are punishment. For others, they are a blessing! When the P90X calendar tells you to take a day off, do it. The days off aren’t just to give you a chance to relax—they are there to prevent overtraining and injury.

Another way in which P90X prevents overtraining is through muscle confusion. If you were a weight lifter and did heavy squats day after day, you would likely overtrain your quads. They would stop responding to the workouts and possible even decline in health. You may even injure them more easily. By switching up the routines from day to day, P90X ensures maximum progress and minimal risk of overtraining.

Overtraining is possible with nearly any workout system. However, by sticking with your P90X calendar and recognizing when your body needs a break, you will find P90X and overtraining to be an extremely rare occurrence.

Overtraining, mostly found in weight trainers, runners, and serious athletes can lead to injury and physical exhaustion. When training, whether for an athletic event or for weight loss, people sometimes get over anxious and quit listening to their body. Being aware of what causes overtraining can help you avoid it and minimize time spent on the sidelines. Listening to your body and being aware of its limits will reduce the chance of overtraining. The truth is: the body only makes improvements during rest times. Yes, seriously. The benefits of all of that heavy lifting and those situps happen once you stop. When you are training, tiny tears occur in the muscles. During periods of rest the body repairs these tears, similar to patching drywall or welding metal. These reinforced areas become stronger than they were pre-trauma and this is where the benefits of training come in.
 
When you fail to give your body time to heal, you not only fail to make progress, you actually start to do damage. Weight training without recovery periods is like punching holes in the wall without taking the time to patch them up. Good fitness routines account for this by having rest days or periods of cross training.
 
Another key in being able to recognize overtraining before it happens is listening to your body. When you don’t pay attention to how your body feels, you increase the chances of injury and other symptoms of overtraining. A twinge of ankle pain may turn into a sidelining injury if precautions are not taken when the pain first starts. Adjusting your workouts to cater to any overly sore muscles or joints will protect you from injury associated with overtraining.
 
Keep in mind this doesn’t mean you have to take a whole day off of exercising every other day. It just means that you don’t want to work the same muscle groups everyday consistently or you may push them too hard. This is why many routines will have you do shoulder and back one day followed by legs the next. If you did shoulders and back three days in a row you would be missing out on the recovery period and pushing those muscles to the point of potential injury.
 
Keeping the science of muscle gain in mind can help prevent overtraining. In order to make progress, your muscles must repair themselves. Without repair comes further damage and possible injury. Overtraining can have you completely out of the exercise game for a long period if not cautious. By learning to alternate workouts and listening to your body, you can prevent overtraining and get the maximum benefit from your fitness routine.
