When running downhill without straining your quads, focus on efficient biomechanics and strengthening exercises. Land your foot under your hips with a slight forward lean from the ankles. Engage core muscles and maintain an upright posture using a shorter stride. Include eccentric exercises like single-leg squats in your training. Start with gentle slopes, progressively increasing difficulty. Utilize recovery techniques including foam rolling and choose appropriate shoes for traction. Master these strategies for better downhill running.
