If you literally do nothing else after you workout in the morning, except play video games the rest of the day, you will feel like you have achieved something.
A huge part of being healthy, eating right, and working out is mindset.
If it makes you feel good, you will continue to do it. You will have positive feelings and thoughts about it.
If it is a chore and too much work and makes you miserable, you will start finding excuses to get out of working out.
By getting to the gym or getting those 2 miles in before your body really knows what hit it, is huge to feeling good about yourself.
It will place importance on working out because if all you do one day is work out, then that is the single most important thing to you.
Your mindset will shift to making exercise more of a priority and it will help you turn working out into a constant in your life.
Take away: Feel good about your laziness and get a good workout if you do nothing else.
