Oh that part. lol...
I have guys that are ranging from 140 - 240 lbs from 5'7" to 6' something. I am around 120 Lbs and 5'5". Believe it or not 180-240 range is not that big or strong as compare to some guys on the street (don't know if that's the Canadian water or what). So some of them would like to know what a smaller person could do facing a bigger guy just in case.
Warm regards
Robert
