A computerized self-training auto-reminding app for creating an always tight core. It graphs your progress and functions like a 24/7 coach training you to “KEEP YOUR CORE TIGHT.” When you hear the reminder alert, tap “Yes" if your core is tight (be honest), tap "Not Really" if your core isn’t tight, or tap “Skip” if not applicable. The app graphs your response history and increases/decreases the next alert interval to match your muscle memory span. You may receive a Surprise Alert between your regular alerts just to keep you honest! You will be amazed how quickly you will be able to maintain a constant tight core! Add a friends email to track each others progress.
