There are two ways to see the Birthday Workout. One is that it's the kind of gift that keeps on giving and you really ought to gift yourself with it. The other is that it's the test that tells you how you're holding up in your fight against time. Performed each year to show you whether you've gained or lost fitness ground. Whichever way you decide to do it the sure thing is that it will deliver a total body burn that will leave you feeling recharged and worthy. Not a bad way to spend a birthday, right?
