A 4-0 thrashing of Gainsborough Trinity was a perfect response to their double defeat to Spennymoor over the festive period.
Armstrong said those defeats weren’t helped by players’ overindulgence in recent weeks.
A team meeting helped iron out their troubles and Armstrong was delighted with the reaction.
“I think that was our most convincing performance to date, it could have been more than four without a shadow of a doubt,” he said to the club’s channel BSAFC TV.
“They have responded exceptionally well. We had a good chat after the two Spennymoor games and we discussed things, and what needed to change.
“Last year was the same over the Christmas period, we didn’t play well at all so that was part of the chat we had.
“I said to them that they have got to start looking after themselves over the festive period better. You can’t enjoy the parties like you use to, you have to sacrifice things.
“I think this performance showed what we are capable of, it could have been six or seven.
“We had gone back to conceding sloppy goals again so the big thing for me was the clean sheet.”
