This document outlines Mike Hui's workout for achieving hard abs. It involves running 3 miles a day with proper form and running partners. The core workout consists of various crunching exercises like regular crunches, reverse crunches, and oblique crunches. It also includes more advanced moves like V-ups, extra special crunches, and holds to engage the abs fully. The routine progresses by increasing the number of repetitions for each exercise daily until it takes over 15 minutes to complete.
