It's time to bulldoze bad habits and bring down the hammer on your midsection. Join NASM master trainer and former pro fitness competitor Kim Lyons for 30 days to reconstruct your core. Incorporate her follow-along workouts into your current routine or complete them on their own to ramp up and build a solid foundation for your next fitness challenge.

These workouts can be done anywhere, anytime, with minimal equipment. You’ll begin with a series of targeted five-minute routines to build your foundation. Then you’ll increase the intensity with 10-minute interval-style workouts to build muscular endurance and power while blasting calories and fat. Kim has expertly designed these workouts to give you the biggest results in the least amount of time possible. She also offers progressions or regressions to meet your needs — beginner to advanced — in order to avoid injury and plateaus.
