Does Interval Training Have Disadvantages?

Interval training is an effective way to improve your fitness level and really kick into gear. You've probably heard about many of the advantages of interval training, but you have probably not heard much about the potential disadvantages of interval training. I regularly use interval training as my regular workout, so I will share with you the possible disadvantages of interval training.

Overtraining

When we interval train, it is easy to overtrain because intervals really push our bodies. To prevent overtraining, you should take at least two days in between each interval training session. Your body will need time to recover. If you overtrain, you will experience a variety of discomforts and will have to take even more time off, so it is important to simply prevent overtraining in the first place.

Am I Pushing Too Hard?

Your body will tell you if you are pushing too hard. Being unusually fatigued and/or unable to sleep well may occur. Just generally not feeling well and not feeling like exercising are possible. You may not be able to eat well and/or may be irritable. Your resting heart rate may occasionally increase. You may have chronic soreness or pains. Chronic respiratory infections or colds may occur. You also put yourself at risk for tendinitis and other overuse injuries.

If at any point during your interval training you experience pain or any other symptoms, stop immediately. There was a time where I got dizzy because I was working so hard that I had become dehydrated. I had not properly increased my water intake for the increased demands on my body. If you experience pain, stop, and apply ice, rest and compression to the hurting area. Also, elevate it, if it is a body part that can be elevated. It is generally a good idea to have all injuries evaluated by a doctor. Sometimes an injury that appears to be just a sprain could actually be something more severe.

Recovering from Too Much Interval Training

If you know that you have pushed too hard and are experiencing overtraining, it is time for a break. You will generally need seven to 10 days to rest your body and allow it to recover. You will not experience deconditioning in this time, so don't worry about this. In fact, in my experience, after a break you will actually come back stronger and more able to conquer your fitness goals. When you return to your interval training, start back a little slower and with fewer intervals and work your way back up to prevent experiencing overtraining again. It is also a good idea to see your doctor just to make sure you did not experience any injuries or other issues.
