Plenty!
Depends what time you are going. I go in the evening around 9 pm and it's fine, but earlier than that it's difficult.
There is ample parking, it's a huge plaza so even if you don't get to park right in front of the gym, there's parking around the other side
Enough lots
There is ample shared parking with Vallarta, a Laundromat and Pollo Campero. However, like most places around town spaces are limited at busy times.
