6. You're doing too much too soon.
Unfortunately, results don't happen overnight. It takes time and consistency to get in shape over the long haul. But how many of us decide that we're going to get in shape and then get totally gung-ho, spending hours at the gym only to find ourselves tired, sore and no thinner after a week or two?
Get-Results Remedy: Be patient. Remember that you're creating a lifestyle change that you can sustain for the rest of your life. While there's temptation to start off doing extra-long and hard wod’s/workouts, don't. Build up to doing those tough workouts gradually as the weeks go by. Not only will this prevent injury and give your body more time to adapt and change, it will also give your life and habits time to change, permanently!
