10-minute core workout

1. Begin lying on your back with your hands extended above you toward the ceiling.
2. Bring your feet, knees, and hips up to 90 degrees.
3. Exhale hard to bring your ribcage down and flatten your back onto the floor, rotating your pelvis up and squeezing your glutes. Hold this position throughout the movement. This will be your starting position.
4. Initiate the exercise by extending one leg, straightening the knee and hip to bring the leg just above the ground.
5. Maintain the position of your lumbar and pelvis as you perform the movement, as your back is going to want to arch.
6. Stay tight and return the working leg to the starting position.
7. Repeat on the opposite side, alternating until the set is complete.

1. Lie on the floor with the knees bent and the feet on the floor around 18-24 inches apart. Your arms should be extended by your side. This will be your starting position.
2. Crunch over your torso forward and up about 3-4 inches to the right side and touch your right heel as you hold the contraction for a second. Exhale while performing this movement.
3. Now go back slowly to the starting position as you inhale.
4. Now crunch over your torso forward and up around 3-4 inches to the left side and touch your left heel as you hold the contraction for a second. Exhale while performing this movement and then go back to the starting position as you inhale. Now that both heels have been touched, that is considered 1 repetition.
5. Continue alternating sides in this manner until all prescribed repetitions are done.

Remember to exhale during this movement. Note: When holding the contracted position, you should look like superman when he is flying.
