Control Resonant: How to Solve the Pulse Fitness Gym Puzzle

The Pulse Fitness gym in the Unknown zone hides one of the six secret hideouts in Control Resonant, sealed behind a wall marked with a purple keyhole symbol. Opening it means using the gym’s cardio equipment in a very specific order, following the workout plan posted inside the building.

Quick answer: Set the treadmill to 0.5 MPH, the bike to 15 MPH, use the vending machine once, set the treadmill to 15 MPH, then set the bike to 0.5 MPH. The wall slides open.

Where to find the Pulse Fitness gym

The gym sits in the middle of the Unknown zone, near West Incursion 21. Get close and the map shows a Secret marker with the prompt “Visit this location to reveal a secret.” The Unknown is one of the more confusing areas to move through, so expect to use your traversal abilities to reach it.

The structure is below street level, making it easy to overlook as you explore the area above. Enter via the alleyway street to reach the front room containing the treadmills.

The full machine sequence

The clue is a two-set cardio plan: a slow stroll, hard cycling, a break at the vending machine, then a fast run and a slow ride. The treadmill and bike swap speeds between the two sets, and the vending machine acts as the water break in the middle.

Go to the treadmill in the front entrance room and set its speed to 0.5 MPH.

Head down the hallway to the back cardio room and set the stationary bike to 15 MPH.

Head back to the hallway and activate the green Limu vending machine once. Leave it unused after that, as the plan allows for just one break.

In the front room, return to the treadmill and set the speed to 15 MPH.

Return to the bike room one last time and lower the stationary bike to 0.5 MPH. The purple wall beside the bike slides open.

Interact with the vending machine only once. The workout plan specifies a single break between sets, and extra interactions break the sequence.

How to know it worked

When the last speed is set correctly, the wall next to the bike slides open to reveal a doorway beneath the keyhole emblem. If this is the last of the six hideouts you have opened, the Backroom Espionage trophy pops at this moment.

Head down the hidden stairs into the basement facility to collect the rewards.

The Health Upgrade Point is the main draw, since collecting three of them increases your maximum health. The basement also holds documents belonging to the shadow organization tracking the Federal Bureau of Control, filling in extra lore that never appears in the main story.
