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.
Ordering pizza.
Tequila.
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.
