If you're working out and not seeing any physical changes in your body, you may need to "polarize your training," said running and fitness expert Jason Karp, the 2011 IDEA Health and Fitness Industry Personal Trainer of the Year.
Polarization involves using recovery to your advantage, said the San Diego-based Karp. Recovery can mean taking a day off or working at a lower intensity. With runners, Karp stresses going all out on hard days and relaxing on easy days.
"Most people — especially gymgoers — make their workouts all in the middle," he said. "It's the same thing every day. With really hard days, you force adaptations that cause stress; then you recover by working easy."
