You can exercise all you want, but if you won't see any progress if you don't give your body proper time to recover.
Your body uses sleep as an opportunity to rebuild the muscles you have broken down through exercise, so making sure you get enough is crucial to success!
If you're an adult, it's recommended you get a minimum of 7 hours of sleep/night. Depending on the intensity of your workout program and your daily life, you may find that you need closer to 8+.
Not only does sleep give your body a chance to recover and rebuild, it will also give your mind some time to relax and take a break to reload for the next day.
Sleep, good or bad, can have a domino effect on the rest of your week. Not only in your workout routine, but in your daily life as well.
Getting the proper amount of sleep on a consistent basis will both accelerate your progress towards your fitness goals and ensure you can keep a consistent mood and energy level throughout the day.
Besides, who doesn't love a good night's sleep?
