That is, High Intensity Interval Grass Cutting.
Here in Central PA, it is finally warming up and I will be cutting the grass for the first time tomorrow. Last year I used it as a workout. Since my lawn slopes slightly, I push the mower and cut in a square. I go along the top, down the slope, across the bottom then sprint up the hill with the mower. Get's a lot of looks from the neighbors but it is a great workout. When it's warm enough to take off the shirt, their odd looks somehow disappear.
