I usually suggest that people do their steady-state cardio on the days that they're not with me; they really don't need a cardio babysitter. When working with athletes, I try to pair the interval with the exertion patterns of their respective sport.

Protein is key in my opinion. Vegetables are a must. Complex carbohydrates have to be used at the right time. Stay away from processed foods, refined sugars, and fruit juices.

Strike a balance between resistance training, intervals, longer duration cardiovascular work, and flexibility. Don't stick with one approach then flip after a few weeks. Mix it up weekly, daily.
