Did you notice what the security light was doing on the main cluster?

Clean and switch keys to rule that out.
If iit were starter heat soak, it would happen elsewhere.
If your PKE is still active, yet you are not using your remote, then it is conceivable that the antenna is picking up the EM interference, and is unsure how to deal with it.
Park farther away from the lines to see if that changes anything.

I always used to like battery cutoffs. However, now with all of the complex electronics with dozens of modules, I am not fond of killing power and then restoring it. A lever blade type provides full power immediately upon lowering it.
The knob type can cause momentary connection then loss as you tighten it, then connection etc. Those "jolts" can cause trouble especially if they occur often.
Steady power, with a boost from a very low trickle type computerized charger, such as Battery Tender, or C-Tek, is a feature of my battery "religion".
I also always make a permanent connection rather than using alligator clips.
Lastly, I make the connection to the car before powering up the charger.
Can't say if any of that truly helps absent some scientific study, but it does avoid surges to the electrical system.

Also trying to think what could be different in the gym routine form elsewhere, as you are suggesting that is the only place that it happens.
Certainly the EM field is of some concern, different key than usual?
does it get handled/ stored differently?
Same shoes as always? Are you sure that you are getting the clutch pedal fully depressed?
Is your door opening sequence different at the gym?
Just trying to rule out simple things first.
Keep us posted.
But monitor the security light when you turn the car off, then when you open the door, then after you lock it, and how do you lock it key or door lock switch? Watch the light as you do each and let us know.
Do you toss the gym bag in or pop the hatch?
