Here's the problem.
(Especially with legs)
You just trained quads or hams a day or two ago, and you go in for your next training session, but those muscle groups are still ridiculously sore (like that immobilizing kind of sore).
You go to stretch prior to your workout, but even moving these muscles is excruciating.
Is it better to leave the sore muscles alone?
Should you stretch them as normal anyway?
Should you stretch them, but lightly?
I experienced this on Sunday from my leg workout Friday and cardio session Saturday. I was unsure of how to handle it. I only just started stretching and doing similar sorts of exercises and warmups six months ago after years of getting tighter and tighter and feeling worse and worse. That warmup session I decided to stretch the bigger muscles, but not as hard as I normally would.
