Fitness stuff is one of those packs that added too little stuff. One new equipment piece that needs max height room to sit in cause it breaks in rain outside. Now as they rarely address previous packs I don't see them adding more less a future pack has a particular interest in fitness like a hobbies expansion.
They have so much from previous packs to be inspired by. They could have added
- elliptical
- spin cycle
- rowing
- hamster wheel (a treadmill in ts2 ps2)
- dance class (rumba?)
- Pilates
- dumbbells
- skipping rope
