Wanna multitask by exercising and making money at the same time? Become a landlord and do your own work. Painting, scrubbing, landscaping, carpentry, etc. all works the main muscle groups. Skip the gym fees, go buy some fixer-upper units, and resolve to do as much of the work yourself. After a few years of that you can retire, sell the units, and do a 1031 into a gym.
