The most exercise I’ve ever had is solo assembling a 295 pound Rogue Fitness Monster Lite power rack and raising it from the horizontal position I assembled it in to the vertical position.

I figured after that much effort I needn’t exercise ever again. I sold it the next week at a loss (cheapest hobby I’ve ever had). Although to be fair I didn’t realize at the time that I needed to buy the barbell and weights too. Lesson learned: stick to the monthly gym membership that I will never use.

The second most exercise I’ve ever had is solo raising my Grizzly 14” bandsaw to standing. Also never used, but at least I never had the heart to sell it.
