I'm currently training for a marathon with a training program consisting of 5-6 workouts for week. It's also varied workouts including pilates, football (read: soccer) and a weights session.
During all of these workouts, I'm not doing any specific leg exercises (squats, lunges etc) to strengthen my legs. My thinking behind this is that adding these exercises will make my legs ache for about 2-3 days afterwards and it might impact my running.
Am I correct in thinking that running with aching legs is a bad thing or should I be adding leg exercises into my weekly workout and just stretch properly before my run if my legs are aching?
