Some surprising things you can do and still reach your fitness goals:
Taking a slice of chocolate cake.
Lying on the couch all day.
Eating a wheel of cheese.
Drinking eight beers.
Staying up too late.
None of these things will stop you reaching your goals as long as you stick to this one rule:
Get back on it the next day.
And the day after that.
And probably a few days after that too — especially if you had beers and pizza.
