A 30-day abs challenge and core workout plan you can follow without looking at your phone. Put it down, press Start, and the coach talks you through every move — around 5 minutes a day, at home, no equipment, no gym. **A COACH THAT TALKS — YOU NEVER LOOK AT THE SCREEN** • A coach voice announces each exercise and how many reps • Form cues before every move ("keep your legs straight…") • Spoken 3-2-1 countdowns with beeps, so a plank stays a plank • Four coach voices, calm or energetic — in English, Spanish, French and Portuguese **A PLAN BUILT AROUND YOU** • Answer two quick questions — get a 30-day plan for your focus and your level • Beginner, Medium and Hard tracks that grow with you • Focused programs: all-over core, lower belly, love handles, upper abs • A short warm-up before and a short stretch after — or switch them off • Too hard today? Swap any exercise for one that trains the same area • Rest days are part of the plan, and they keep your streak **SEE WHAT 30 DAYS CHANGE** • Day 7: the moves feel familiar. Day 15: you hold longer. Day 30: a finished chapter — then level up or pick a new focus • Streak, calendar, workout history, calories and time trained • Optional weight & BMI tracking with trends • A home-screen widget for your streak, and a daily reminder at the time you choose • Finished workouts save to Apple Health, if you allow it **EVERYTHING INCLUDED** • All 30 days of every track — Beginner, Medium and Hard • All four focus programs: all-over core, lower belly, love handles, upper abs **ON YOUR WRIST (APPLE WATCH)** • Works on its own — no iPhone needed: the 30-day starter track is built into the watch, so you can start Day 1 straight from your wrist • Start a workout on your iPhone and your watch mirrors it live — phase ring, exercise and countdown • Pause, Skip and Quit from your wrist, with a tap on every phase change and the last 3 seconds • Watch-face complications and the Smart Stack keep your streak and current day a glance away • See your heart rate while you train — shown on your wrist only, never stored • Every day you finish on the watch counts toward your plan and streak **HEALTH NOTICE** 30 Day Abs is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a qualified healthcare professional before starting an exercise program if you have health concerns. **YOURS, PRIVATELY** • Workouts run offline; data stays on your devices unless you choose account backup • Optional free account backs up progress and syncs across devices • We never sell your data. Delete your account any time in the app. Build your routine one short session at a time. Results vary by person and consistency.
