Look Your Best

Kate Hudson's longtime trainer Nicole Stuart says a Triad ball is the perfect tool for people who need to take their workout with them when they travel. "When deflated, they don't take up too much room in your suitcase and they're easy to blow up," says Stuart. "Use them to do modified crunches and oblique exercises wherever you are."

BONUS TIP:
For best results, add a 10-minute Triad ball workout to your regular cardio routine 3-5 times a week. (Even when you're at home!)
