## What is Plank Challenge?

Get a stronger core in just 30 days — no gym, no equipment, no excuses. The 30 Days Planking Challenge guides you from your very first 20-second hold all the way to a 10-minute plank with a progressive, day-by-day program you can do anywhere.

Hands-free voice coaching counts you in, calls the halfway mark, and pushes you through the final seconds — so you never have to look at your phone mid-plank. Just press start and hold.

WHY YOU'LL STICK WITH IT
• Streak Shields automatically cover one missed day per week, so a single skipped session never breaks your momentum.
• A clear 30-day calendar shows every workout at a glance.
• Personal bests track how far you've come.

FOUR DIFFICULTY TIERS
• Beginner: 20 seconds → 2 minutes
• Intermediate: build real endurance
• Advanced: longer, tougher holds
• Elite: 4 minutes → 10 minutes

BUILT FOR YOUR WHOLE DAY
• Full Apple Watch app — train with your wrist, leave your phone behind.
• Home-screen widget keeps your streak front and center.
• HealthKit sync logs every session as core training.

SIMPLE, FAIR PRICING
• The Beginner tier is completely free.
• One-time Pro unlock adds the Intermediate, Advanced and Elite tiers — pay once, own it forever. No subscriptions, ever.

Whether you're rebuilding strength, fixing your posture, or just want visible abs, two minutes a day is all it takes. Start the challenge today and feel the difference by day 30.
