I recently moved from Portland to Los Angeles, and am taking advantage of the weather and the opportunities to workout outdoors. However, I feel like I need to add something extra. I discovered ExerciseTv and love Jillian Michael's and Jackie Warner's routines, but I feel like I need more to re-structure my workouts (so as not to plateau). I also lift a few sets of light weights once a week. Any suggestions for effective at-home workouts?
