No way, brah.
I've been practicing my striking at a Thai boxing gym, and if it went to the ground it would be curtains for fatty.
The only thing going to the ground .......would be you ,once he cracks your skull with a punch..
Out of shape or not? That man has trained longer than you've been alive... It's gonna take many ,many ,years to even think you can imagine throwing something at him that he doesn't see or hasn't seen a million times..
But I will give it to you ..You do have a wicked imagination.
