As per hippietrail's comment:
No I stayed there for almost one month and never found something. It's pretty labyrinthine though, so I could've still missed it.
So we can presume a free outdoor gym is either non-existent or extremely hard to find. However there's a very cheap spa with a gym called "Gym Spa Rosy Da Lat". As per Tripadvisor reviews, the price for a full day's stay is 50,000 VND or ~2.5 USD.
