Read this story & then you will understand.
My mom introduced me to ballet at the age of 5 at our local YMCA. I went in kicking and screaming and came out saying I would never go back. The following week, she took me back. I took ballet classes the next 13 years and learning body placement & posture helped me control the pains I felt from Scoliosis, having no cartilage in my knees, intense shoulder pain from heavy bookbags & more.
Going into college, I continued taking dance technique classes in the evening and received a Minor in Dance. This is why I love my story. One day, I saw men taking a beginning ballet class. Clearly, they looked like they didn't belong. I asked one of the teachers and she said those are football players. The coach requires all Freshmen players to take a beginning ballet class to help them become more aware of body placement, core stability & increase their flexibility.
There you go! These same football players were taking a low impact workout (Barre/Pilates) to combine with the lifting/cardio (Interval Training). These same people who may go on to the NFL.
Now, ask yourself again why haven't you started my program. I combine my Core 3 Values of Posture, Body Placement & Flexibility into my workouts.
