JILLIAN'S TIP OF THE DAY
Challenging Yourself From Your Feet on Up
Another factor to consider when you vary your intensity level is your "base." This refers to the way in which you plant your feet on the floor. A wide base — placing your feet wide apart — helps stabilize your body. Working through an exercise with a wide base makes it easier to maintain form throughout reps. A narrow base, on the other hand — placing the feet together — makes any exercise more difficult, because your core and other muscle groups have to work harder to maintain a neutral — or balanced — body position.
