Fantastic workout!! Fantastic instructors! The instructors are very knowledgeable and explain things so well for beginners as well as more expirenced boxers to keep the class just right for each person. I was very happy with the welcoming atmosphere and felt like I belonged my very first day! Whenever an instructor noticed I was new, they immediately came up to introduce themselves and welcomed me to Knockout! Just Awesomef!!!
