체크포인트
-The lower back stays in contact with the floor throughout.
-Legs stay straight with toes pointed.
-The bottom leg hovers and never rests on the floor mid-set.
-The tempo stays fast but even, not flaily.
흔한 실수
-Letting the lower back arch off the floor as the legs fatigue.
-Bending the knees into a cycling motion.
-Kicking through a tiny range that removes the training effect.
-Holding the breath for the whole set.
프로그래밍 노트
-Use 3 to 4 sets of 20 to 40 seconds, or 15 to 25 switches per leg.
-Reduce the range or place hands under the hips if the lower back lifts.
-Good as a core finisher or in conditioning circuits after strength work.
