should ur fist be clenched always or clenched just before impact on a opponent?

Would like to know aswell,

I have been clenching my fist on impact and let it relax when i'm not punching. But some people tell me i should alway's use clenched fists.


For me, parrying punches with relaxed fists is alot easier than with clenched fists

For me yes. Try and move with anything clenched and see how slow it feels.
