Ballet bar not raising fitness level

[IgnorantBliss]

I've been asking around, and so far I seem to be the only one with the problem. Using the ballet bar doesn't raise the sims' fitness level (the fit/fat level, not talking about fitness enthusiasm or body skill). No matter how long they use the ballet bar, gain body points and such, their fitness level doesn't move one bit. I'm suspecting it's a hack conflict, but I'm not sure from which hack. The only obviously fitness related hack I have is fitness4all, and it's not the culprit, because removing it doesn't fix the problem. Any ideas?

Seems like hack conflict, as I have no problem raising fitness level using ballet bars, buyable or career reward.

Once again, I point the blame squarely at tight pants.

I have a colleague who wears similar tights to the gym. His fitness level seems to be fine, though. Although, who knows what it would be without the pants, though. 

I'm waiting for the inspiration to start weeding through my hacks to find the culprit.

Looks like the problem has been fixed. I think it was an expired skillinator that caused it, although I'm not 100% sure because I also removed or updated a couple of other hacks at the same time.

Well, it falls short of a definitive controlled experiment, but I suppose it doesn't matter, given that the problem no longer exists.
