The fastest way to have a six-pack is to run?

To maintain a good posture, don't get too close to the front of the treadmill.
The heel touches the ground first for slow motion like walking and jogging, while fast running requires a touch of the forefoot to reduce the impact.
Be careful not to stride too much during sprints and shorten stride length when running in the mountain mode.
Keep the forward posture in case of postural deformation when you are tired.
Don't move your arms left and right around your body. Keeping your arms and legs parallel is important for healthy running and strong health.
it is said that the fastest way to have a six-pack is to run? is that so? whats your idea?
