Many of you have heard it before… and I will repeat it. Sleep is VERY important to our health, productiveness, sanity, fitness goals, etc… and the list goes on and on. I have heard clients suggest they will shorten their sleep so that they can get up earlier and exercise. Bad idea. Unless you were sleeping 8 to 10 hours, cutting back on sleep so you can get your exercise in simply defeats the purpose. Sleep is our time for renewal and for our bodies to reboot. Our immune system is recharged, and the muscles that we broke down during our workouts are rebuilt. Read more about it here http://www.webmd.com/sleep-disorders/guide/important-sleep-habits
Again, start with small goals. Even an extra 20 – 30 minutes of sleep will make a difference. But consistency is key; try it for at least a whole week, and see how you feel.
