I love my heart rate monitior - it works so well to track how I'm doing. It's the Polar F7, and it's connected to Discovery Vitality too, so that I can earn extra Vitality points. It shows when I'm exercising in a fatburning zone, and when I'm in a fitness zone, which is great - so that I can strive to do half-half per workout. Also, often when I feel I've exercised enough, and I check how I've done - it motivates me to try burn a couple more calories - really helps me challenge myself, which is great!
This week, I've been doing about 25 minutes of cardio, then 25 minutes of circuit strength training, and then ending on the PowerPlate.
Today I felt energetic and supercharged my workout with some extra running on the treadmill and extra time on the stepper (gosh, that thing kills me!!!) - and I managed a calorie burn of 539 calories in just over an hour. Yay!
