Heart-rate training maths as an API. The max-heart-rate endpoint estimates maximum heart rate from age by the three common formulas — Fox (220 − age), Tanaka (208 − 0.7 × age) and Gulati (206 − 0.88 × age, validated for women). The zones endpoint returns the five training zones (recovery, endurance, aerobic, threshold and maximal) as beats-per-minute ranges, computed either as a simple percentage of the maximum heart rate or, when you give a resting heart rate, by the more accurate Karvonen heart-rate-reserve method. The target endpoint computes the target heart rate for any intensity, by percentage of max or by Karvonen. You can pass an age (and choose a formula) or give your own measured max heart rate. Everything is computed locally and deterministically, so it is instant and private. Ideal for fitness and running apps, wearables and gym equipment, coaching tools, and cardio training programmes. Informational only — not medical advice. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 4 endpoints. This is heart-rate maths; for BMI, BMR and calories use a health-calculator API and for running pace use a pace API.

Swimming API
Swimming maths as an API, computed locally and deterministically — the SWOLF, threshold-pace and per-100 m numbers a swimmer, coach or training app works a set out with. The swolf endpoint scores stroke efficiency for one length: SWOLF (swim + golf) = the strokes taken plus the seconds taken, and like golf lower is better — gliding further per stroke or swimming faster both cut it, so a 25 m length in 18 strokes and 30 s is a SWOLF of 48. Because it is pool-length and stroke dependent, the score is normalized to 25 m so lengths in different pools compare. The css endpoint computes Critical Swim Speed, the swimmer's threshold pace, from two all-out time trials: CSS = (distance1 − distance2) ÷ (time1 − time2) — the classic 400 m and 200 m test, where 6:00 and 2:50 give about 1.05 m/s, a 1:35 / 100 m threshold; training paces are then set as offsets from CSS, the swimmer's equivalent of a runner's threshold or an erg's 2 k pace. The pace endpoint gives speed and the per-100 m pace swimmers actually quote (time ÷ distance × 100), so 100 m in 1:30 is a 1:30 / 100 m pace at 1.11 m/s. Everything is computed locally and deterministically, so it is instant and private. Ideal for swim-training and coaching tools, lap-tracker and triathlon apps, and fitness calculators. Pure local computation — no key, no third-party service, instant. 3 compute endpoints. For running pace use a pace API; for indoor rowing a rowing API.

Indoor Rowing API
Indoor-rowing (Concept2 erg) maths as an API, computed locally and deterministically — the watts, split and calorie numbers a rower, coach or fitness app works a piece out with, using the published Concept2 relations. The split-to-watts endpoint turns a 500 m split into power: on an erg the power is fixed by the pace, not the stroke rate, so watts = 2.80 ÷ pace³ where the pace is the seconds per metre (the split ÷ 500) — a 2:00 split is about 202 W. Because power goes as the inverse cube of pace, small split gains cost a lot of watts: pulling 1:50 instead of 2:00 is roughly 270 W, not 220. The watts-to-split endpoint inverts it — pace = (2.80 ÷ watts)^(1/3), split = pace × 500 — so a target wattage maps to the split on the monitor and a rower's power compares directly with a cyclist's or any other watts figure. The calories endpoint applies the Concept2 calorie formula, Cal/hr = (watts × 4 × 0.8604) + 300, where the +300 is a fixed resting-metabolism term that makes the erg's count run higher than pure mechanical work; 200 W is about 988 Cal/hr, roughly 494 calories over 30 minutes. Everything is computed locally and deterministically, so it is instant and private. Ideal for rowing and erg training tools, coaching and leaderboard apps, and fitness calculators. Pure local computation — no key, no third-party service, instant. Concept2 model — a machine estimate, not lab calorimetry. 3 compute endpoints. For running pace use a pace API; for cycling a cycling API.

Powerlifting Score API
Powerlifting strength-score maths as an API, computed locally and deterministically — the Wilks, DOTS and IPF GL numbers a meet, gym or training app uses to compare lifters across bodyweights and sexes. The wilks endpoint gives the classic Wilks coefficient (1996) and score: total × 500 ÷ a fifth-order polynomial in bodyweight, with separate male and female curves — long the federation standard for "best lifter", a 100 kg man totalling 600 kg scores about 365. The dots endpoint gives the modern DOTS score (2019), the same total × 500 ÷ polynomial idea but fitted to updated data with a fourth-order curve that is fairer across the weight classes and not skewed to the middleweights, now the default in most raw meet software. The ipf-gl endpoint gives the International Powerlifting Federation's current GL Points (2020): 100 × total ÷ (A − B·e^(−C·bodyweight)), with separate constants for sex and for raw (classic) versus equipped lifting, the official metric at IPF championships. Everything is computed locally and deterministically, so it is instant and private. Ideal for meet-management and scoring software, gym leaderboards and training-log apps, and strength-sport tools. Pure local computation — no key, no third-party service, instant. 3 compute endpoints. For one-rep-max estimation and plate loading use a strength-training API.

Barbell & Lifting API
Barbell- und Gewichtheber-Mathematik als API, lokal und deterministisch berechnet – die Plattenbeladungs- und Prozentzahlen, die ein Lifter, Trainer oder eine Fitness-App an der Hantelbank ausrechnet. Der Platten-Endpunkt löst das alltägliche Rätsel im Fitnessstudio, welche Platten auf jeder Seite für ein Zielgewicht aufgelegt werden müssen: 100 kg auf einer Standard-20-kg-Stange bedeuten 40 kg pro Seite, zuerst die schwersten als 25er und 15er; 102,5 kg fügt die 1,25-Mikroplatte hinzu; und wenn ein Ziel mit den vorhandenen Platten nicht erreichbar ist, lädt es die nächstmögliche Kombination und teilt das Defizit mit, sodass Sie nie raten müssen. Es funktioniert in Kilogramm oder Pfund (225 lb auf einer 45-lb-Stange sind zwei 45er pro Seite), mit einem benutzerdefinierten Stangengewicht und einem benutzerdefinierten Plattensatz. Der Prozent-Endpunkt wandelt ein One-Rep-Max in das tatsächlich zu ladende Arbeitsgewicht um: 80 % eines 100-kg-Maximums sind 80 kg, und die Abfrage eines Fünf-Wiederholungs-Gewichts ergibt etwa 85,7 kg über die Epley-Formel (1RM = Gewicht × (1 + Wiederholungen ÷ 30)) – fünf Wiederholungen liegen nahe 86 % des Maximums, zehn Wiederholungen nahe 75 %. Der Aufwärm-Endpunkt baut eine Rampe von der leeren Stange bis zum Arbeitssatz bei etwa 40, 55, 70 und 85 %, jede auf einen ladbaren Schritt gerundet, wobei die Wiederholungszahl sinkt, wenn die Stange schwerer wird. Alles wird lokal und deterministisch berechnet, also sofort und privat. Ideal für Entwickler von Fitnessstudio-, Krafttrainings-, Powerlifting- und Fitness-Apps, Workout-Logger und Coaching-Tools sowie für Entwickler von intelligenten Hantelbänken und Plattenrechnern. Reine lokale Berechnung – kein Key, kein Drittanbieter-Service, sofort. Exakte Mathematik, keine Simulation. Live, nichts gespeichert. 3 Compute-Endpunkte. Für die Schätzung des One-Rep-Max aus einem Satz verwenden Sie eine Strength-API.
