One of the best ways to build your core is to do things on unstable surfaces. So whether standing on one leg, using a BOSU Trainer (that blue bubble-shaped apparatus you see at gyms), using a stability ball rather than a bench, doing push-ups on medicine balls rather than the floor, or using TRX equipment, all these methods require stabilizer muscles and core strength.

This will be very hard at first… you’ll likely fail a lot… but over time, your core will be so solid and strong that you’ll be able to cut back the amount of time you spend doing dedicated core-only exercises.

I decided to try the 21 day fix and am so glad I did. Due to an injury I wasn’t able to complete the exercise part of it. I still lost weight and owe so much of my success to Kim. She motivated and encouraged me when my injury was really getting me down. She always had time to answer my questions and she checked in with me daily. What I loved the most was that she held me accountable! I really don’t think I would have stuck with it on my own.
