Resistance bands are an excellent tool for training your core muscles and improving flexibility.By adding resistance, bands force your core to engage and stabilize your body during a wide variety of movements. This helps to build strength from the inside out. They are also incredibly effective for stretching and increasing your range of motion, which in turn boosts flexibility.Whether you're performing a controlled twist, a seated row, or a leg press, resistance bands offer a simple yet powerful way to challenge your body and achieve a more stable, flexible foundation.
