This book(The Art of Tai Chi: John Kong Tai Chi 100 Forms By John K. H. Kong) listed detailed body movements when doing Tai Chi, which is one of Chinese kung fu :
8. Natural Standing, breathe naturally.
9. Sit, breathe out, body on left leg, right leg goes backward, turn head to right and look back. Keep breathing naturally.
I think it is incorrect to use "look back" here, because "look back" means that you looked at the path behind you along which you have travelled, you can only do this if you have been moving. The author should use "look behind" here.
Am I correct? Thank you.
No, either "look back" or "look backwards."
"Look behind" is not right.
I can't find my $10 bill. I will look behind the dresser.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
