I've been curious for awhile now, curious about how much of a workout it actually is when I cut the grass. So, I geared up (heart rate monitor, watch, foot pod) for cutting the grass this afternoon. I suspect there are other factors that would actually apply to this that would yield different results. Such as height of grass, temperature, humidity, etc... But for today, for my roughly 1/4 acre lot, I walked 1.16 miles, took 2,844 steps, averaged 1.6 MPH, and spent about 100 calories.
So, if the definition of cross-training simply means to do workouts that emphasise different muscle groups and different functions of your body, grass cutting does fit that definition. Maybe I won't complain so much about cutting the grass now. :) Nah, I'll still complain.
Oh yeah, it was a self propelled lawnmower. It would be more of a workout if it was a push mower, but in my 40 years of cutting grass, this is my first self propelled mower - not going to give it up!
