What would you do if you were violently grabbed from behind in a bear hug over your arms??? The answer is a throw. Note, I had this lesson a few times and today the fundamental lesson finally sunk into my thick skull. Also, I was back working out with the heavy weights, someone that out weighs me by more than 50 lbs. My partner was Alex, a Romanian Black Jack dealer at the Hard Rock Casino.
Like a guy with a grudge, bam!, into my back, he’s got me in a Grizzle bear hug, my arms were locked down, and I felt that I may be body slammed if I don’t act quickly. Just like I was taught, I quickly base out. I drop down and curled my arms. My shoulders wobbled a little bit as he thrashed me side to side. I shrugged my shoulders up, it gives the space I need, I step to one side, all in seconds, I then slip my front left leg behind his back knees. From my semi crouched position, I stood up quickly while grabbing his pant legs at his knees while dumping him over my shoulder. I launched him, off over my back shoulder with velocity, right into the mat. Actually, I stopped while I had him in the air.
Of course, nobody was injured. We didn’t actually execute the throw. This was a typical fundamental’s class.

This is a great lesson. Sometimes I do find it hard to do this move when the person is much bigger then you.
