I decided that I wasn't happy with the uncertainty of these apps that tell me how many calories I have been burning when I work out. I mean, how do they know? I could totally be going through the motions one day and working my butt off the next day and I still give myself the same credit for the workout when I log it into myfitnesspal. Just like with my kitchen food scale, I needed to know what a serving size was. So with my workout, I needed to know how many calories I was REALLY burning with each workout.
My new Heart Rate Monitor is quite a motivator! I got a fairly basic Polar FT4. I added in my height, weight and age and it does the rest! There are many different styles and ones with a TON of bells and whistles on them. You could pay hundreds! Mine, I just wanted to know how many calories I was burning. I feel no need to upload my workout info into my computer and map everything out. I don't want to be that analytical. Maybe some day, but I am happy with this one right now.
Every time I am in my target heart rate zone it quietly beeps to let me know I am where I am doing the best work. It is pretty motivating to work hard in each workout just to hear that little beep. I thought the chest strap was going to be a little distracting, but it really isn't. I hardly notice it at all as I am sweating profusely. :)
My only wish is that I had gotten one sooner. I really love it!
