A 100 kg bench at Basic Fit is not a 100 kg bench at Westside Barbell. GymCred™ applies a peer-reviewed* Authenticity Multiplier across 80+ gyms to convert any lift into its real, gym-adjusted personal record.
Select where you train, what you lifted, and how much. We'll do the humbling — then you can share the damage.
Every chain sorted into the six tiers of credibility — from S-tier iron temples to the F-tier ego zone.
All 83 chains, ranked by how much a personal record there is worth in the real world. Search for yours.
| # | Gym Chain | Tier | Authenticity Multiplier | 100 kg bench = | Signature Trait |

↕ Scroll for all chains. Multiplier reflects equipment honesty, clientele seriousness, chalk policy, and grunt tolerance.
Two gyms enter, one PR leaves. Pick a matchup, a lift, and a weight — find out whose iron actually counts.
Deep-dive dossiers on the chains that matter, scored across the five pillars of credibility.
A genuine 140 kg bench press claimed at each chain. Watch it evaporate.

The ratios are linear. The despair is not.
On top of the gym multiplier, each movement carries an Ego Inflation Factor. The leg press did not earn its number.
A rigorous, totally-not-made-up framework refined across thousands of unsolicited gym observations.
We assess plate calibration, bar whip, machine assistance, and whether the "20 kg" plates are suspiciously light. Rubber-coated vanity plates incur penalties.
Field analysts measure grunt tolerance, chalk policy, mirror-selfie density, and the ratio of people training to people filming. A lunk alarm is an automatic downgrade.
The pillars are blended into a single Authenticity Multiplier, then cross-multiplied with the per-lift Ego Inflation Factor to yield your real PR.
"I benched 140 at Basic Fit and felt like a god. GymCred told me my real PR was 14 kg. I've since started crying between sets like a real athlete."
"Finally an objective way to prove my garage gym (1.20×) is more legit than my brother-in-law's Equinox membership. Christmas dinner was tense but I was right."
"My entire personality was a 200 kg leg press. GymCred adjusted it to 50 kg and then Jules' Homegym appeared at 0.005× and somehow I felt better about myself."
The cardio cinema, the €19.99/month pricing that funds zero chalk, the Smith machines branded as "free weight area", and the fact that you can comfortably take a phone call mid-set. The iron simply does not respect you back. It's nothing personal — it's mathematics.
The lowest multiplier ever recorded. A yoga mat, a resistance band still in its packaging, and a single adjustable dumbbell that doubles as a door stop. A heroic 200 kg "lift" there converts to 1 kg. We re-ran the numbers twice out of respect for Jules.
Certain establishments — Prison Yard (1.75×), Temple Gym (1.55×), Westside Barbell (1.50×) — are so hostile to the human body that lifting there at all is an achievement. The ambient suffering tax means a PR is worth more than the number on the bar.
Yes, and the leg extension is worse (0.15×). We have never met a person whose leg press number reflects reality. Your 400 kg leg press is a 100 kg leg press wearing a costume.
On X, WhatsApp, Reddit and Threads, yes — your result rides in the share text. On Facebook, no: it strips custom text and only shows our standard preview card. Blame Zuckerberg, not us. Copy-to-clipboard always carries the full burn.
The asterisk on "peer-reviewed" refers to a peer named Kevin who also lifts. Kevin reviewed it. Kevin approves.
If you have to ask, default to 0.30×. If your gym has a sauna nicer than its squat rack, 0.20×. If the front desk sells protein cookies but no straps, 0.15×.
No. This is satire. Lift wherever you want, including Basic Fit, which is a perfectly good gym. A PR is a PR. Please do not cite GymCred™ in arguments with your personal trainer.
Run your numbers through the index, discover the crushing gap between your claimed PR and your real one, then inflict it on your group chat.
