Aldershot boss Dean Holdsworth praised defenders Anthony Tonkin and Troy Brown after watching his side win 2-0 at Plymouth.
Central defender Brown powered a header past home keeper Jake Cole from left-back Tonkin's pacy free-kick after five minutes.
Holdsworth's delight doubled when Josh Payne sent Cole the wrong way from a 53rd-minute penalty, won by Michael Rankine.
Reflecting on the first goal, Holdsworth said: "That is one of the areas we needed to improve on. We scored three goals from set-pieces last season which is not enough for us.
"It's about the delivery and execution and I was delighted with Troy's finish and Anthony's delivery into the box because the goal gave us confidence.
"It was a crucial time for us to get that second goal. I said to them at half-time, `If there is going to be another goal make sure it us' because this place is very vocal."
Plymouth boss Carl Fletcher felt errors proved to be the undoing of his side.
"It was obviously not the start we wanted but goals change games and a couple of mistakes have cost us," he said.
"When you play League Two football it's important you don't give away free-kicks because it's a chance for teams to put the ball into your penalty area.
"I was disappointed with the way we dealt with that and the way we defended it."
