The other day, as I was working out at home, I remembered that i needed to write a blog for physics. I was doing an exercise in which I have one foot on a box about 4 ft. high, and i jump, pushing off the box with my foot. As I am in mid air, I switch feet, landing on the box with my opposite foot. I realized that throughout the drill, my net work is zero because I have no change in Kinetic Energy. My initial velocity was zero and my final velocity, my velocity at the peak of my jump, was also zero. This makes sense, because, as I was doing work up, gravity was doing the same amount of work down, resulting in a zero net force. Thinking of this, helped me to take my mind off the strenuous task that I was doing.
I like how you incoporated physics into something as regular and simple as exersising.
