I am a huge fan of your shape I have only used it 4xs but love it so far. With one exception. If I am doing a work out in the personal training and decided I want to do another type of work out with in personal training it will not save the sessions I complete. I can never make it through the sessions which is super aggravating. Is there anything I am doing wrong? OR is this just a glitch that hasnt been fixed? I am also wondering if it will be fixed soon because I am seriously considering trading it in if its not.
