Query: extremely boring!

I consider myself being in a good shape, not great, just good. I do not work out on a regular basis, and I am 35 years old. I couldn't finish this workout, I did only 3 miles: it was just extremely boring! You just literally walk 4 miles raising arms and doing some slight variations of walking movement from time to time. Even completely unfit people could have a bit more variety and complexity of movements.
