mix lower body strength training with running, such as repetitive squats and lunges with weights, also since running requires a strong core, the core training is crucial. I personally like swimming for my core training because I was a professional swimmer when I was teen....but you can do the trainings that suit your best! 總而言之，不要單一跑步，要加入力量訓練，噢，我還忘了一點就是瑜伽，瑜伽非常重要，不僅對flexibility也對core，我知道男人往往忽視瑜伽，但其實因為男人的flexibility本就不強，所以更加需要！
My few cents, hope it helps! It's nice to seeing runners in the place where full of the smell of money lol........
