I was physically and mentally tired yesterday so I decided to take the day off from work and exercise. I skipped my planned workout and took a long nap, watched a movie, and just did nothing. It felt great to just relax. I did stretch a bit in the evening but it was very restorative compared to the usual yoga practice I do.
I really believe that when you eat healthy and exercise with adequate intensity daily your body tells you when to rest. If you listen to your body and do get some rest the reward is a boost in energy levels and a completely focused mind until your body needs rest again.
If you feel the need to take a day off all the time then start eating that healthy and getting some form of restorative exercise daily and that will change faster than you can imagine.
