cross arm defense

[Trainer Monkey]

You cant get any power from that defense,so there's no reason to respect you and hold off,Id either jab you,or press you,I could easily do both

I think the only guys to really be succesful from that posture were naturally exceptionally strong tough guys

Even then,your putting so much torque on your shoulder blades,ie your rotator cuffs,long term,I think Id rather take the punch.You have to arm punch rather then putting your body behind it
Ive seen the occasional guy who can pull it off,but theyre the exception,not the rule,its sort of like Ali's hands down style,Ali can do that,because he's Ali,you aint,so dont do that.
