Hi cjbear!
Great to know that you've joined alli and are hopeful and excited about getting healthier! You should be proud! Know that we at alli are committed to providing you with all of the tools necessary to promote long-term weight-loss success!
Although I haven't heard of Helix, I do know that WiiFit has been a great addition to individuals workouts and if indeed effective. That said, from your comments, it sounds like you were feeling the workout and that is a sure sign that it is working!
Be sure to include both cardio (walking, jogging, swimming, biking, hiking, etc) as well as strength training workouts into your week to promote heart-healthy benefits, weight loss and over-all strength/toning. The alli website provides helpful animated demos, workout ideas, recipes for healthy eating, etc to help you reach your weight loss goals!
Please let us know if you have any other health/fitness questions. You can also visit us on the "Discuss with a specialist" forum for exercise, diet, or even pharmacological questions.
Thanks and best in health,
