Body-Changing Tips From Tracy Anderson

Tracy Anderson is well known for her take-no-excuses personality and her superhuman-toned bod. Her workout philosophy relies on the science of how your various muscle groups work together — Tracy engineers her moves to operate in certain, distinct ways so that problem areas respond and are eventually strengthened and toned. She emphasizes how important it is to use your muscle groups in combination with each other — not simply looking at an ab exercise where you only target your abdominal muscles, but focusing on engaging the surrounding muscle groups as well.

All are simple to do where you are and when you've got the time — no fancy machines required. No excuses here! Ahead, five body-sculpting moves that every girl can master.
