This restriction can also have adverse effects on the knees and ankles, increasing the risk of injury. Adopting shorter strides significantly amplifies the energy expenditure required to maintain a given speed. This increased energy demand can result in early fatigue.\nBeing mindful of the range of motion in your leg and hip movements will allow you to have better technique. Incorporate sprints or accelerations to encourage more dynamic movements of the back leg. Including mobility and proprioception exercises would also be beneficial.\nVisualize your rear heel being tethered to a balloon, lifting it behind you with each stride.",

To compensate for the backward-leaning posture, the gluteal muscles may be excessively engaged, leading to muscle tension in that region. A backward-leaning torso can shift the center of gravity backward, overloading the leg muscles. This will reduce the ability to propel the body forward, resulting in a loss of efficiency and an increase in energy expenditure.\nEngaging the abdominal muscles will help support the lumbar region and maintain a posture with an intention to move forward. Also, ensure that your pelvis is neutral, neither tilted forward nor backward, to avoid overuse of the gluteal muscles.\nDuring the run, focus on vertical alignment by imagining an invisible cord pulling upward from the top of your head.",
