You can't see them. But they are there, lurking in the shadows: that merciless string of holidays ready to ruin any hope you had of sticking to your fitness routine. By the time you're free of their clutches, three months and 13 pounds have slipped by. Not this year. What you need is a plan to guide you through those trouble zones mapped out by someone who won't accept excuses, who doesn't know the meaning of the word holiday and who lets nothing stand in the way of train- ing, 365 days a year. Consider yourself drafted.

With military-style classes all the rage among trendy fit- ness clubs, SELF deemed it our patriotic duty to give you a boot-camp-like regimen to help stave off the havoc the sea- son can wreak. So we recruited Patrick Avon, President of the Sergeant's Program, a drill-instructors-for-hire operation in and around Washington, DC, and Tory Allman, director of personal training at Frog's Athletic Clubs in southern California, where classes carry such intimidating albeit inspiring names as "Green Beret" and "Navy SEALs." Together, they've devised this getserious, seize control week.

Each morning 0600, of course starts with "Roll Call," when the day's calorie burning assignment is handed out. (You choose from a list of aerobic activities.) Next comes "Gimme Ten," a muscle toning session. Drop and do it any time that day. Upper and lower body work alternates to guarantee a full body workout by week's end. Last, "Lights out" lets you hit the abs before hitting your bunk.

As you rise through the ranks, so does the intensity. If you can't go the distance on a given day, do what you can and stay at that level. By week's end, you can go back to your usual routine knowing that when your fitness flags, you have what it takes to take charge. Now, move it out!
