Gym is a very capital-intensive business. A decent treadmill costs 150 to 200k, spin bike 40k huko, smith machine kitu 200-300k. That's the cost for single items na hujahesabu weights na vitu zingine za kawaida. Gym pia inataka a large space, which costs more to rent, na instructors, bathrooms, maji kwa wingi including hot shower so tokens pia utakuwa unanunua kununua. I'm not trying to discourage you. Unless you want to start small na vitu kama basic dumbells, barbells, na u-concentrate na cardio exercises, you need at least afew hundred thousand shillings to start. Na hapo you'll be doing some serious bootstrapping.
