This is a personal preference thing. I suggest experimenting with a lot of different grips. There are a few standard grips, though.
Alright, When you are in bottom guard. What's the proper hold to avoid them from raining blows? or standing up.
Also, same as in full guard. Do I hold double under hooks? or hold around the head and arms?
I can get into attacks from any of these if you want. Still, play around with them. Developing a good guard is about finding what works for your body type, flexibility, mindset and personal level of comfort. There's no single answer.
- Both hands behind the head.
- One hand on the back of the head, one hand on the arm.
- Both hands on one arm.
- One overhook, one underhook.
- Double underhooks.
- One arm free, the other hooking under the opponent's knee.
