If you do some easy cardio and stretch your entire leg thoroughly the next day after leg workout BEFORE they lock up on you the pain is diminished greatly. Once they lock up, on day 2 after workout for me, it hurts too bad to stretch them effectively. If you can stretch before they are too sore, you will be able to walk and sit on the can with much less pain. I do some easy cardio immediately after legs, then stretch for 10 minutes, and on perfect scenario, do easy cardio the next morning and stretch out for 10 min at least. The times I don't get to stretch the day after sucks.
