It's not all that important, but it's something that Mark teaches to begin with. You should include it a few times though at the start and end of articles as I think James mentions in that video (if memory serves me correct).
From what I saw though, it looks like you're having trouble with putting the keywords in for reviews right? They're always the tough ones, and here are some good things you can put into the article at the top, middle and bottom which include the keyword. Don't take them word for word or anything, but use it to generate more ideas for yourself.
"I noticed on a few forums the other day that people were looking for a XXX review"
"So I decided to write me own XXX review for you out there looking"
"This is my XXX review"
"Below is a quality XXX review, that covers this... that..."
"While doing my XXX review, I found that..."
"Before writing my XXX review..."
"While planning how I'd write my XXX review..."
"To finish off my XXX review, I'd like to ..."
"That is the end of my XXX review"
"I hope my XXX review was of benefit to you"
You can usually put them in somewhere if you try. Just make it sound natural and don't force it if you can't do it. Having the 1% keyword density definitely won't hurt your rankings or anything like that, so it's not bad. PM me if you need anymore help with the article writing process, once you understand the basic structures, it becomes somewhat easy to keep producing more.
