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.
Kellan Gillis was the first celebrity that I worked with - that didn't hurt. Working out after that with Jennifer Lopez was huge in terms of just the platform it gives you. So I think when you get those opportunities, you have to be respectful of them, and you have to try not to just cash out.
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.
My mom - when I complained about my weight, she asked me if I wanted to keep complaining or do something about it. Then she took me to Weight Watchers when I was 10 years old, meetings and all!
Not to sound corny, but if life is a sport, if you're moving to dive on a fumble or pick up a basketball in transition or pivoting to grab your toddler so he doesn't fall into a pool... those are real life movements.
Make it a joint effort. Doing a workout with a partner or trainer can motivate you to reach your goals.
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.
I am a big believer in taking responsibility for your actions. I tell my kids every day to 'own it' - 'it' being whatever they've said or done. At some point in your life, you are in charge. You call the shots. You decide to eat or not eat.
Sleep plays an important role in overall well-being and especially in recovery during particularly intense training.
