I told my FI that I'd like a heart rate monitor for Christmas, but I am not sure that he got one for me... I'd really love it so I could figure out exactly how many calories I am burning. I'll be interested to hear how much you burn during T25! I finished week 6 and am onto week 7! Can't believe I have been following it for this long! It feels so great and my body is definitely showing a difference! I fit into an old red dress that was too small at the beginning of November and I was able to zip my wedding dress up this weekend YAY!! I had some "back" fat that did not look good... but I am just soo happy it actually zipped! now to get rid of the back roll lol! I stepped on the scale this morning and it said I gained 4 lbs over the weekend, but theres no way! I am hoping after eating healthy and exercising today it'll be back down to my normal weight tomorrow!
