Generators have a significant amount of load to make them viable and work best at constant speeds.
Huge amounts of load at the start and then momentum usally makes it more efficient. This is great for endurance training, but you would have to mess with a fair bit of engineering for weight machines to work well.
At that point you might as well just make them preform labour like splitting wood.
Isn’t that the purpose of a gym?
