Every individual’s anatomy is different which is why we have designed a customizable, physical therapy approved core program. The iFour Core app addresses specific areas of your core to help you develop the strongest core imaginable without injury. Each workout is under 10 minutes, is suitable for all fitness levels, and can take place in the home or at the gym. As a member of the iFour Core app, you will receive new workouts every day, nutrition guides, and support. FREE 7-day trial for new members! HOW IT WORKS: After completing the iFour Core fitness test, you will get a core strength rating. This rating is broken up based on muscle fibers worked (intrinsic, rectus, obliques & transverse). The iFour Core app customizes the exercises each day based on your fitness test performance and current level of core strength. WHAT MAKES US DIFFERENT: Life is full of surprises, plateaus, and challenges. We created this app with this in mind allowing you to recalibrate your individualized workout formula at any point you feel necessary. Unlike other programs, this is not simply just hitting “reset,” and repeating the same exercises from previous days. This is a full recalculated algorithm taking you from your new “starting point” with a proven plan of attack to help you once again improve. iFour Core Features: Workout & Fitness Planning • Functional yet challenging core rotations, ranging from 5-10 Minutes! • Includes regressions to decrease difficulty and progressions to advance the exercises as you improve. • 323 unique core exercises. • 137 additional core exercises with 6 different pieces of equipment to choose from. • Video demonstrations of all 323 core exercises. • Designed for all levels, whether you are coming out of physical therapy or an elite athlete! • Take the fitness test and as you get stronger, unlock more core exercises prescribed for you. Tracking & Fitness Motivation • Workout along with J, a seasoned trainer for celebrities, professional athletes, and others. • Track your daily progress in both your Fitness Test and Workout History. • Share your results on your favorite social media platform. • Keep up to date and learn with the latest iFour videos.

The call

The clearest difference is price: iFour Core at Free against Daily Ab Workout's $9.99. iFour Core also leads on rating (5.0 vs 4.8) and update cadence (every 2 months vs every 4 months). Daily Ab Workout's advantage is in-app purchases (none vs 2) and ratings volume (1.3K vs 28). On review sentiment, ads and device support there is nothing between them.
