How the Cindy Calculator Works

"Cindy" is one of CrossFit's most iconic — and most accessible — benchmarks: a 20-minute AMRAP (as many rounds as possible) of 5 pull-ups, 10 push-ups, and 15 air squats, with no equipment beyond a pull-up bar. Your score is the number of rounds (plus any extra reps) you complete, so more is better. It's a test of muscular endurance and pacing rather than a short sprint. This tool takes your round count and places it into one of five tiers, adjusted for age.

An Honest Note on the Data — Why Cindy Is Different

Most calculators in this suite are built on a peer-reviewed study of the CrossFit population, which gives measured percentile thresholds. Cindy is not in that study. There's no published percentile dataset for it, so its tiers come instead from community coaching consensus — the round counts widely reported by coaches and gyms. At peak age we use, for men, roughly 13 rounds (Intermediate), 17 (Advanced), 20 (Superior), and 25 (Elite); women's tiers sit about 2–3 rounds lower for the reasons below.

What that means for you, honestly:

• These are rules of thumb, not measured percentiles. Published Cindy numbers vary a fair bit between sources, partly because pull-up and push-up standards (strict vs kipping, full range vs partial) differ from gym to gym. Treat the tiers as an approximate guide.
• Don't compare tier-to-tier with the study-based calculators. Grace and the runs use measured percentiles; Cindy uses coaching guidance. Being "Advanced" on one isn't equivalent to "Advanced" on another.
• The percentile, distribution curve, and "fitness age" are modeled on these community bands — so they're doubly approximate here. Read them as illustrative, not precise.
• Movement standards change the numbers a lot. A Cindy done with strict pull-ups and full-depth push-ups will score several rounds lower than one with kipping pull-ups and shallow reps. The tiers assume honest, full-range Rx movement.

Step 1: Enter Your Rounds

Cindy is scored in rounds — one round is 5 pull-ups + 10 push-ups + 15 air squats (30 reps). Enter the rounds you completed in the 20 minutes, plus any extra reps of a partial round. The standards assume Rx movement: standard pull-ups, chest-to-floor push-ups, and squats to at least parallel. Scaled versions (banded pull-ups, knee push-ups) will score higher but aren't comparable to these tiers.

Step 2: Match Your Rounds to the Tiers

Your round count is compared to age-adjusted marks and assigned to one of five tiers (more rounds is better). At peak age, for men:

• Low — Fewer than about 13 rounds. Below the typical intermediate mark. Often pull-ups or push-ups are the limiter — scaling them keeps you moving.
• Intermediate — About 13–16 rounds. Around where many athletes who Rx Cindy land, with steady pacing.
• Advanced — About 17–19 rounds. Consistent sub-70-second rounds with efficient transitions and few breaks.
• Superior — About 20–24 rounds. Near-continuous work; strong push-up endurance and minimal rest.
• Elite — About 25+ rounds. Games-level bodyweight capacity. See the note below.

Women's marks sit about 2–3 rounds lower at each tier. These band edges are the widely cited community targets, mapped onto the five-tier scale and adjusted for age — approximate guides, not measured percentile cutoffs.

What "Elite" Means Here — an Honest Caveat

"Elite" here is a coaching rule of thumb — roughly 25+ rounds for men — not a measured top-1% cutoff. It means near-continuous movement for the full 20 minutes with almost no breaks, which very few recreational athletes sustain. The true competitive ceiling is higher still: top CrossFit Games athletes have logged 30+ rounds, and the famous 38-round score Chris Spealler posted when Cindy appeared at the 2009 Games is essentially the outer edge of what's humanly possible. For nearly everyone, the honest targets are the community ones: intermediate athletes land in the mid-teens, and anything past 20 rounds is genuinely strong.

Why Women's Standards Are Lower Than Men's Here

Cindy is the opposite case from the barbell sprints. Where Grace and Isabel scale the load by sex and contain no bodyweight movements — letting women reach essentially the same times as men — Cindy is built entirely from pull-ups and push-ups and squats, moving your own bodyweight. Pulling and pressing your own mass, especially the pull-ups, favors higher relative upper-body strength, where the average difference between the sexes is largest. So women typically complete a few rounds fewer than men at the same level, and the tiers here are set about 2–3 rounds lower for women — reflecting community round counts, not any assumption of equality. (This is the same direction as Fran, which also has pull-ups.)

Why Age Matters — and a Note on the Borrowed Curve

Cindy is a 20-minute test of muscular endurance and stamina — pull-ups, push-ups, and squats repeated until the clock runs out — and that capacity fades with age. Standards are therefore scaled so an older athlete isn't measured against a 30-year-old's round count.

The honest part: there's no age-banded Cindy data, so the peak-age round counts are the community bands above, while the shape of the age decline is borrowed — an endurance/muscular-endurance curve (roughly 1% per year from the mid-30s, accelerating after about 70) drawn from how masters athletes decline in sustained efforts. It's a defensible stand-in, but both the base counts and the age shape are estimates, not measurement.

Why Bodyweight Isn't Used to Set Your Tier

Cindy is bodyweight-only, so lighter athletes generally have an edge — there's less mass to pull and press for 20 minutes. Even so, the tiers are not bodyweight-adjusted: CrossFit has no weight classes, and the community round counts are reported as flat numbers. So bodyweight can influence your score, but it doesn't change the standard you're measured against.

The Cards

• Your Score & Tier — your round count, your tier, and how many more rounds you'd need to reach the next one.
• Fitness Age — the age whose typical round count matches yours. Because this capacity peaks in the mid-20s to mid-30s, a score above any age's typical mark reads as "peak-fitness level"; lower scores map to an older fitness age.
• Population Comparison — a modeled percentile: roughly what fraction of athletes in your age group you'd out-round.

Where You Fall

The distribution curve places your score within a modeled, illustrative spread of athletes of your sex and age, shaded into the five tiers, with more rounds to the right. It's a visual sense of "how rare is this," not a literal population census.

Data Sources and Verification

• Community coaching consensus — Cindy's tier bands come from round counts widely reported by coaches and gyms (beginner ~10–13, intermediate ~13–16, advanced ~17–19, superior ~20–24, elite ~25+ for men). These are rules of thumb, not a measured percentile distribution.
• Cross-checked across sources — The bands reflect the range reported across multiple coaching write-ups and community fitness-level tables, which vary partly due to differing movement standards.
• Not the peer-reviewed study — Unlike Grace and the runs, Cindy is not in the CrossFit-population percentile study; this is the main reason its tiers are softer and shouldn't be compared tier-to-tier with those calculators.
• Masters endurance-decline research — The age-adjustment curve is borrowed from established masters endurance/aging data.

Limitations and Important Caveats

• Community bands, not measured percentiles — The biggest caveat: tiers are coaching rules of thumb, coarser than the study-based calculators, and not equivalent to them tier-to-tier.
• Movement standards drive the score — strict vs kipping pull-ups and full vs partial range of motion can swing your round count by several rounds; the tiers assume honest, full-range Rx movement.
• Modeled percentile and distribution — the percentile, curve, and fitness age are illustrative estimates layered on top of the community round counts.
• The age curve is borrowed — from masters endurance research, not CrossFit athletes directly.
• The sex gap is approximate — women's tiers are set ~2–3 rounds lower from community data, not a precise measured difference.
• Bodyweight and grip matter — lighter athletes and those with better pull-up/grip endurance have an edge that the flat tiers don't adjust for.

Disclaimer:
This calculator provides an estimate based on community benchmark data and a modeled age curve — not peer-reviewed measurement. Cindy is a high-rep bodyweight effort that loads the shoulders, elbows, and grip heavily over 20 minutes. Warm up properly, pace yourself, scale the pull-ups and push-ups to your ability, and stop if you feel faint, dizzy, or a sharp joint pain.
