You know perfectly well that exercising is beneficial to your lungs, heart, muscles and bones. But could you imagine that you will improve your skin by keeping fit? Exercise increases the flow of blood to your skin, which helps your body remove waste. Gradually, you can gain healthy complexion and nice blush on your cheeks! It also releases endorphins and reduces levels of hormones known to negatively impact skin structure. Exercise has even been shown to improve acne. In addition, sport is a great and free remedy for depression. As an added bonus, exercise can leave you with a rosy glow that lasts hours after your workout is over. Just make sure you drink enough water while exercising. You will feel dehydrated if your body loses at least 1% of water. Always carry a bottle of water with a lemon slice; it will renew your water balance. A person should drink not less than 2 liters a day, but during intense exercises double this amount to feel comfortable.
However, do not torture yourself by hours of severe training! Perhaps, yoga will become your cup of tea. I also recommend to consult a qualified specialist to determine the program which suits your needs best.
