Lots of change going on for the Obamas as they gear up for a new life in the White House. One thing Barack and Michelle won't alter as they adjust to their new roles and routines, though, is the way they approach fitness.

We told you recently that President-elect Obama works out six days a week for about 45 minutes. We also told you he'd love to go longer -- 90-minute workouts would be ideal. But here's some new skinny on how the 47-year-old Pres-to-be keeps his shape: He pumps iron and prefers lateral pull-downs, one-arm dumbbell curls, shoulder presses, and leg presses. For cardio, he takes to the treadmill or the basketball court. Since kicking his smoking habit (well, almost -- he did admit to bumming a few smokes during the campaign), Barack has become even more committed to being fit.

Michelle, also fierce about her fitness, starts her workouts as early as 4:30 AM. She likes to sweat and opts for a mix of cardio and weight training. It's three times a week for the almost-First Lady, who gives 90 minutes to her exercise window. Her favorite fitness gadgets: Free weights, treadmill, stair-stepper, and spin bike. Often exercising with a buddy or a personal trainer, Michelle says exercise is more than just physical for her -- it's therapy too. More on Michelle here, in this AOL Health gallery.

Seems the Obama girls are following in their parents' fitness footsteps. Malia apparently favors soccer, and Sasha picks gymnastics and tap. Both girls play tennis.
