The source outlines a one-week training and nutrition strategy, called the "Kickstarter Week," specifically designed for older adults to combat age-related muscle loss, known as anabolic resistance. This resistance makes muscle less responsive to growth signals, requiring a higher protein intake (~0.4 g/kg per meal) than younger individuals. The plan integrates three short, full-body resistance training sessions per week to re-sensitise muscles, alongside daily step goals and a consistent protein rhythm spread across three to four meals. The document provides detailed exercise breakdowns, substitution options, and progression rules, emphasising that this structured approach uses the temporary window of muscle sensitivity after exercise to maximise rebuilding effo ...
