Friday- almost everybody’s favorite day of the week. As if you needed a reason to love it any more, it’s also a rest day on my favorite training program by Hal Higdon. Today, spending some extra time relaxing is not only allowed but encouraged. Without a day for your muscles to recover, you won’t be able to improve. Your muscles will actually build in strength as you rest. If you feel guilty about taking the day off, it might benefit you to learn about the recovery process and how vital it truly is to your overall performance. So go ahead and sleep in or watch a little TV or maybe take that nap that you usually have to postpone because of your workout. On a rest day, your body does all the work for you. All you have to do is relax.
