Running on a treadmill does burn calories, but it might not specifically focus on the muscles that help reshape your body after 45. To effectively reduce belly fat, you need strength-based movements that keep your core active throughout. Standing exercises are perfect for this—they sculpt your midsection while building muscles that boost your metabolism.

The simplicity of these exercises is their greatest asset. Forget machines or non-stop cardio; just rely on your bodyweight and dumbbells to push your core and legs to exert more effort. Each repetition trains your body to remain stable and robust, activating your abs with every movement.

By dedicating yourself to these exercises for 30 days, you’ll experience more than just a flatter tummy. Your posture will improve, your balance will become sharper, and you’ll move with more strength in everyday activities. Discover how to harness the power of standing strength.
