You could probably get electrical energy that is needed to run a gym (lights, accountant pc, vending machine) if you just install generators in all of this gym's exercise equipment

A brand new rider makes around 50w off the couch. 100-200w functional threshold power is normal for someone who rides casually but regularly. Pro racers are doing like 5 w/kg so around 300w for a smallish person.

600w electrical output requiring 700w cycling power output is not sustainable human power output. TdF riders will usually output 1kwh over their full (4hr ride) day. Enough for 100 toasts

It can still be worth adding generators and wiring to exercise machines to offset energy consumption
It seems like a lot of extra overhead for marginal benefit.

If you get 15k hours and 1500kwh out of the machine, if electricity rates are 20c/kwh, that is $300 in savings. It's not amazing, but maybe "there's some appreciation value for members for the clean energy"

Though apparently a horse can travel just 20-30 miles per day, while an average cyclist could do 60+.
A horse on a suitably adapted "bicycle" could easily travel 60+ miles; a cyclist without their bicycle would be closer to 20-30.

i just want a stationary bike that can charge my phone.

Most stationary bikes have a flywheel. You could 3D print a gearing set to run a small generator (like this one or DC) off if it. There are tutorials out there about how to set up it up.

I actually did that with an actual bicycle and one of those "make any old bike a stationary bike" stand things. Harvested an old motor out of...what was it, a printer or something? Photocopier? It was the upper-left third of something that used to be office equipment, and built the circuit out of a 7805's datasheet with an extra big capacitor on the generator side. It charged phones. It was jank AF though. All it did was offer 5V at I have no idea how much current on the power pins of a USB Micro-B cable.
