has anyone ever mess up some ones calf by using the lock down because one of my student mess up one of other students calf by using it while going for whip up to old school sweep
Some of the long, scrawny, skeleton legged suckers can grind my calf pretty hard with the lockdown, but never anything but bruises, or a muscle spasm if they tweak it.
What was the injury?
I've never had an injury from lockdown until last week when I was rolling with Eddie. He tried whipping up and when I tried stuffing it he switched to whip down and my knee popped out. No major damage to my knee but I did recieve a tear in my calf muscle and pulled hammy. I had a pre exsisting issue with my calf, so that could have played a major role in my knee popping out. So yup it can happen.
I've had some soreness here and there, so far noone I've applied it to has been hurt **knock on wood** but I tend to go easier on the smaller folks and the newer students (lockdown for people new to feeling it can be a bit uncomfortable). Hope ur classmate feels better soon.
Matters what you mean by messed up. I've had my calf get very tender and stiff for a few days. It wasn't from any type of sudden motion like whipping down/up. It was just from drilling half guard with full resistance from my partner. Being in the lockdown for a while will make you sore if they're really locking it down. Eddie has mentioned tales of people tapping from the lockdown.
I do gi under Royce gracie network and only me and 2 others actually use the lockdown.. When I got put in it and was stretched out on both legs from one o the guys who also does it my legs were extremely tender the next day. If you're not very flexible or have leg problems I think you could even tap people just from being in lockdown (correct me if I'm wrong)
