Thanks Rachel.
I have to mention that I do agree a bit with the previous poster in that while a real gorilla press lift is by far the most impressive, the kind of overhead lifts such as those you mentioned with arms locked lifting from a table or chair are still really great and if you could add some of those in the future as well that would be appreciated!
I know loads of the members here that would buy clips with most kinds of overhead lifts.
Keep up the great work!
