Mondays are always "yard work" days for me. Today I decided to wear my Polar HR Monitor to see if YW really burned calories or got my HR into a good burning zone.
If I can say one thing about myself, it's that my heart and lungs have been in great condition for quite some time, regardless of my weight see-sawing. So, I just assumed YW didn't really do anything for me.
OMGoodness!

I didn't realize how much my heart was working. 2 hr or 120 minutes, burned 700 calories and was in the zone for 1 hr 15 mins of it. I was above my targeted HR I think the other 45 mins. No kidding. I am happily surprised and now understand why I'm a bit fatigued at the end of it every Monday.
I knew YW was great for the upper body with all the raking, etc. but I didn't expect to burn calories like this or have my average HR be 133 and the highest was 159.
Now I have one more reason to enjoy working in the yard.
