I've always encouraged my clients to be creative about fitness. When a business meeting runs late or your child is home sick from school, squeezing in a workout requires more flexibility and resourcefulness.

One option that's perfect for days like these: EA Sports Active, a personalized workout program for the Nintendo Wii game system. (Not familiar with Wii? It's an interactive video game; you stand in front of the screen, and using a handheld controller, you can watch your avatar, or game character, move along with your movements.) I recently teamed up with EA Sports to help develop this program, and I'm thrilled with the results. It features exercises that will improve strength, cardio, coordination, agility and balance. It includes 20 different strength exercises (from biceps curls to lunges to squats) as well as customizable cardio routines, which include a variety of activities like inline skating, walking/jogging, tennis, cardio boxing, basketball, volleyball and more.

All these options mean a more effective workout for you. Instead of sticking with one activity, say walking, and working only the muscles involved in this activity, you can target more muscles by choosing different activities. The result: You'll get a more complete workout, which will help you tone up all over, avoid injury and burn more calories.

There's even a 30-Day Challenge, which consists of circuits that change each day, automatically adjusting to your fitness level. The program will offer you feedback on your progress, and I'll also be giving you clear instruction on the various workouts as well as motivation and positive encouragement. For more information on the game, which will be in stores on May 19, check out EA Sports Active.
