Nothing really worth having in this life ever came without a price; fitness is certainly no exception. If you want it bad enough you have to be willing to sacrifice ease and convenience for a little planning, sweat, and hard work. Calories will always be more difficult to burn than to consume, however the results of healthy eating and working out regularly will always outweigh the alternative.
So do something healthy today! Start making healthy lifestyle changes that will ultimately result in a longer, healthier life. Stop making excuses, and start seeing results. You can do it!
