I first tried Xtend Barre at Sense of Space in Subiaco, Western Australia with the wonderful Catriona and fell in love with it. Actually it is the only class I have done because it isn't where I live.
The following short workout is presented by Lorna Jane and instructed by Rockell from Xtend Barre and I love doing it every day as I always feel lengthened and energised after the workout, but I would recommend that you limit this to 2-3 times a week if you are just starting out.
Also please concentrate on your form (look in a mirror if you can) and go only as far as your body will allow you to. "Perfect form is the key to impressive performance!"
Always consult your healthcare professional before beginning any exercise program.
