Once you have assessed your functional fitness and core stability, you can design your own program based on your needs, goals, and preferences. To make your program effective and safe, it's important to start with a warm-up that includes dynamic stretches, mobility exercises, and activation drills for your core and other muscles. Choose functional exercises that mimic or enhance the movements you perform in daily activities, sports, or goals. Vary the intensity, volume, frequency, duration, and complexity of your functional exercises to challenge your body and avoid plateaus. You can also use different equipment such as kettlebells, dumbbells, bands, balls or TRX to add variety and resistance to your functional exercises. Don't forget to include core stability exercises that target all the layers of your core muscles in different planes of motion with varying levels of difficulty. Finally, finish with a cool-down that includes static stretches, relaxation techniques, and recovery strategies for your core and other muscles.
