The in-store gym has five official tracks: Hold to Eat, Speed, Multi Eat, Calories, and Reach. Calories are the currency that buys them. Multi Eat is described as reaching up to x12. No public first-party page lists prices, per-level gains, or a required order.
Match the purchase to the delay
Run one compact shelf without changing upgrades. Separate the time into travel, aiming, repeated input, and chewing through the target.
| What slowed you down | Track to read | What is official | What is not published |
|---|---|---|---|
| Clicking over and over is uncomfortable | Hold to Eat | The track exists | Whether holding works before you buy it, and the cost curve |
| You walk across empty floor more than you eat | Speed | The track exists | Gain per level and the cap |
| The food stays targeted but needs many bites | Multi Eat | Up to x12 | Price of each step and how it hits every object |
| You keep sidestepping to reach pieces on a shelf | Reach | The track exists | Distance per level |
| The next purchase is far away compared with the route you have left | Calories | Calories are the gym currency, and this track exists | The exact income formula and whether it affects cash |
Buy one step. Repeat a similar shelf or pallet. Write down the level before, the level after, the displayed cost, the panel wording, and the date. Leave a cell blank if the UI does not show it.
Why guides disagree on the first buy
Published priorities are not the same. One overview puts Multi Eat first, then Reach, and treats Speed as later because reach might reduce walking. Other walkthroughs refuse a fixed order and start from the delay in front of you, often Hold to Eat or Speed for a new player and Multi Eat once bite count is the limit. That disagreement is useful. It means the official game did not publish a universal build.
A name is not a formula. The Calories track does not prove a specific multiplier. The x12 ceiling does not reveal what x12 costs. A result from a party does not automatically apply to solo play, because teammates can remove travel you still have to do yourself.
When each track tends to matter
Early on, input comfort and movement show up in every later section. Hold to Eat is the track to test when repeated clicks are the problem. Speed matters when finished sections are far apart. Multi Eat becomes more attractive as shelves and large foods demand more bites. Reach matters when the shelf shape, not the bite count, keeps interrupting you.
Late in a clear, a direct speed or bite upgrade often has less time needed to pay for itself than an income upgrade. Still read the live Calories panel before you skip it. Buying Calories at the end of a nearly finished attempt may have little time left to matter.
Labels from videos that are not on the official list
An October 14, 2026 playthrough mentions stomach, cash bonus, a treadmill, a vacuum, magnets, and carts alongside multi, reach, and speed. Those extra names are not in the official five-track gym description. Do not hunt them unless the current gym or shop shows the same label. Multi, Reach, and Speed in that video line up with official tracks. Stomach and cash bonus might be the player's names for Hold to Eat, Calories, or a separate shop. That is not confirmed.
The upgrade tier list is an editorial bottleneck ranking, not an official power list. Each track also has a short entry under Gym Upgrades.
