Recently, Nicole Winhoffer according an interview to US Weekly!
She says on working out with Madonna...
"We warm up always! I change her program every week. This is important to shock the body. Without change, you can’t achieve results. We love to work on triceps, obliques, and of course, my favorite part – the butt! One of our favorite moves is the plank on chair butt press. We get into the plank position with one foot on a chair and the other leg bent with knee on the ground. Kick the bent leg back and return the knee to the ground. It’s a full body move and a butt-lifter!
The beat dictates my movement and rhythm for her program. One of my favorites is Offer Nissim’s remix of Frozen. It is such a sick beat and gets our adrenaline going."
