The 21-Day Lock-In is a structured fitness challenge designed to help you build strength, improve flexibility, and create real consistency in your routine. Over the course of three weeks, you’ll complete five days of strength training each week, with targeted flexibility and mobility work incorporated throughout the program to improve range of motion, recovery, and overall performance.
This challenge is about locking in on your goals, building discipline, and creating habits that carry beyond the 21 days.
This challenge is about building a strong, flexible body you can maintain — not burnout, extremes, or overtraining.
