If so how has it impacted your workouts? I am very dubious of what my AW has been logging in my workouts. I do a lot of non traditional cardio, and I'm not sure if it is basing my calories of of the gyroscope or HR. Since I am also getting into resistance training with a eye towards getting lean I really want a semi accurate picture of calories out. I was under the impression that HR monitor straps were expensive but it looks like the going rate is $50-100 which is doable. If it gets me much better metrics I have no problem spending the money, but I just want to hear from people first. Those who have them what is the best brand for the money, and what is the best brand money no object?
