The post guides you through matching your workouts and eating habits to your body type to maximize muscle gain, fat loss, and overall fitness results.

The Great Lock-In is a TikTok-driven end-of-year challenge that encourages people to build consistent habits in fitness, nutrition, sleep, and mindfulness from September through December.
