I’ve always been a big proponent of high-intensity , interval training (HIIT) because of the beneficial effect it has on your metabolism when you’re resting . Think of doing wind sprints . Maar, when I interval train , tot nu, all I would do is get my cardio workout going as fast as possible for 60 seconden, then I back off for the next 60 seconden, alternating back-and-forth like this for 20 minuten of zo. The problem is that my historical way of interval training is not very scientific . Am I really getting my heart rate up enough ? Am I really letting it slow down enough ? Tot nu, it was all just guessing . With the Fitbit Charge HR , you can train and make sure you actually hit the Peak heart-rate zone before you back down to the Fat Burn zone .

The Andreus' allegation was not supported by the eight other people present, including Armstrong's doctor Craig Nichols,  or his medical history. According to LeMond, he had recorded a conversation,  transcribed for review by NPR , in which Armstrong's contact at Oaklety, Inc., Stephanie McIlvain, corroborated Betsy's account. However, McIlvain contradicted LeMond's allegations and denied under oath that the incident ever occurred.
