You might be training hard almost every day for two to even three hours a day.
Results are getting better all the time and nothing seems to be possessing a threat to your health.
There is one big threat, lack of sleep.
Many of us don't get enough sleep which possess a risk for getting all kinds of unwanted symptoms.
First of course is that your exercises usually won't go well at all when you exercise tired.
The main problem is that your body doesn't get enough time to rest to recover from your last workout session.
Your immune system also suffers, if you don't get enough sleep.
As a result you'll get sick a lot easier if the period of sleeping too little goes on for too long.
If you are sick, you cannot exercise, which will start to affect your results quite fast.
The other main problem you might be facing when not getting enough sleep is the overtraining syndrome.
When you workout hard and don't get enough rest your muscles won't recover, but this isn't all there is to it.
When you continue exercise tired, your body is working with those unrecovered muscles, and as this goes on the exercising starts to wear your muscles down.
Your results will start to down as a result of this, as the recovery from the last exercise session simply doesn't happen.
So it is really important when exercising hard to get enough sleep.
There are times when you are feeling really tired to stay at home and sleep, instead of going to gym or elsewhere to exercise.
