I NEVER WRITE REVIEWS BUT HAD TO THIS ONE TIME. IF U WANT TO BE CHALLENGED WITH A GOOD, HARD WORK OUT, DON'T BUY THIS DVD!IT IS SO SLOW MOVING AND PAUSES BETWEEN POSES. I AM AT A BEGINNER LEVEL AND STILL DISLIKED THE ROUTINE. I DID THE WHOLE VIDEO AND NOT EVEN A LITTLE BIT SORE THE NEXT DAY. WISH I COULD RETURN! IF ANYONE CAN RECOMEND A GREAT, CHALLENGING, FAST PACED VINYASSA STYLE DVD, PLEASE LET ME KNOW!!!!
