One payment. No rate limits. Transparent WebP in two styles. Built-in alternatives and progressions.
Every classic-style image ships with a true transparent background. Drop it on white, dark mode, a brand color, a photo backdrop — no masks, no compositing, no "white square on my dark UI." We haven't found another exercise dataset that ships this.
Same file. No per-theme asset variants, no canvas tricks, no runtime compositing. images/classic/one-arm-kettlebell-floor-press-peak.webp.
Every exercise ships with regression_of and progression_of relations. Walk up and down a progression ladder with one lookup — no backend, no coach logic.
Filter by equipment, body part, or hand-pick a set — it's all in the JSON. No endpoint, no rate limit, no waiting on our CDN.
Every exercise is tagged for safety — knee_safe, shoulder_safe, lower_back_safe, no_axial_load. Build rehab-friendly UIs without a custom classifier.
JSON. SQLite. TypeScript types hand-written or generated. Same data, three shapes.
