28‑Day Curve Starter is for naturally slim or “thin but soft” women who want bigger glutes and a tighter waist without starving or living on cardio. Train 3x/week for 30 minutes, follow a simple glutes‑not‑gut carb plan, and track waist, hips, and strength. This isn’t a weight‑loss challenge; it’s your on‑ramp from thin‑but‑soft to strong, curvy, and confident.
