Any ideas on drills I can do?

Make a normal full back swing then take your right hand off the club and swing hard through to a full finish.

Almost impossible to make out of sequence movements doing that. Everything falls naturally into place; nothing forced or contrived.

A couple of these swings before the real thing has the added benefit of loosening you up nicely. Failing which, a Beer, or several, might help.
