If you are exercising properly, you will probably feel tired after your workout. The physical benefits of exercise are created because you stress your body to a level it is not used to. Your muscles actually suffer micro-tears, and need time to repair themselves so they are better and stronger.
This is when the rewards really happen. Your muscles, in a vain effort to keep from suffering such injuries in the future, repair themselves stronger than before. Your strength improves, all of your organs become healthier, and you benefit in a number of ways.
Unfortunately, this process can also leave you feeling tired and lethargic after your workout.
There are a few ways to prevent this from happening. First and foremost, make sure you are getting plenty of sleep. This does not only apply to the night before you plan to exercise. Sleep is not something that can be “caught up” on. If you do not get 7 to 8 hours of sleep on a nightly basis, the damage you do to your body and your mind cannot easily be undone.
In other words, sleeping 5 hours a night during the week, and then trying to cram in 20 to 25 hours of sleep over the weekend does not erase the negative health effects of your poor sleep habits Monday through Friday. So make sure you are sleeping properly 7 days a week.
Your tiredness and the accompanying aches and pains you receive after exercise could be a sign of lack of hydration. You sweat to lower your body temperature when you exercise. This can quickly sap your hydration supply. You should drink lots of water before, during and after exercise, and this single practice could eliminate your tired feeling afterwards.
Proper nutrition is also required not only to fuel your workout, but to allow your body to repair properly afterwards. This means eating more fresh vegetables and fruits, more grass-fed beef and wild-caught fish, and less refined sugar, white flour, salt, processed foods and fast foods. When your body does not receive the nutrition it needs, the chances that you will feel tired and lacking in energy are increased.
You should also make sure you do not work out the same muscle groups on back-to-back days. Your muscles need a minimum of 24 hours to repair after you tear them down. This is true whether you are strength training or performing aerobic exercise. This is one of the many reasons why personal trainers recommend working a particular muscle group on Monday, Wednesday and Friday, and alternate muscle groups on Tuesday, Thursday and Saturday.
Remember these obvious but often neglected tips, and you can drastically reduce the times you feel tired after a great workout.
