Proper execution of heel hook and leg bar...

[Bjjexpertise@be]

How should I have my legs placed when performing the heel hook and the leg bar? Should I have my legs placed just like if I were executing the armbar?

That's a big question. Since there is a great chance you could blast someone's knee out pretty easy by mistake I would advise getting an instructor to show you these techniques.
