Where to find the Pulse Fitness gym
The gym sits in the Unknown, the upside-down version of the city. Reaching it depends on story progress, so if you cannot get there yet, read how to get to the Unknown first. Look for the purple Pulse Fitness sign, and flip gravity if you find yourself outside an art gallery instead.
The workout board
Through the doorway on the right inside the gym is a board titled “Workout Instructions.” Each note maps to one machine setting:
- Relaxing stroll: treadmill at 0.5 MPH.
- Furious cycling: bike at 15 MPH.
- Break: use the vending machine once.
- Invigorating run: treadmill at 15 MPH.
- Leisurely ride: bike at 0.5 MPH.
Guides spell the vending machine brand differently (“Lime” or “Limu”), but it is the same machine: the one you use once between the two sets.
Solution in order
- 1. Set the treadmill near the entrance to 0.5 MPH.
- 2. Set the bike at the back of the gym to 15 MPH.
- 3. Interact with the vending machine one time.
- 4. Set the treadmill to 15 MPH.
- 5. Set the bike to 0.5 MPH.
If nothing happens, you most likely used the machines out of order or touched the vending machine twice. Walk through the sequence again from step one.
Rewards
A hidden passage opens and leads downstairs to the secret hideout. It holds a permanent Health Upgrade and the “Procedure For Work Orders” document. This is one of six hideouts; the rest are covered in our secret hideouts guide, and the trophy side is in the trophy guide.
