Pompey will be happy to return to Fratton Park on Saturday following a gruelling week on the road.
A trip to Derby was followed by a trek up to Barnsley, with four points collected from that pair of fixtures.
John Mousinho admitted that the relentless League One schedule does have an impact on his table-topping squad.
But ahead of a home clash with Lincoln, he believes that Pompey’s unbeaten opening has provided them with plenty of belief.
The Blues boss said: “It does take a physical and mental toll and we’ve adapted training to ensure we have fresh legs.
“But coming from those two away games – against sides we expect to be up there come the end of the season – with four points has provided a real boost for everyone.
“We’ve given a really good account of ourselves and so there are many, many more positives for us to take.
“The Football League schedule is brutal and relentless – I know exactly what it’s like with all the travel and games.
"It does take a physical and mental toll and we’ve adapted training to ensure we have fresh legs."
“There’s a demand on teams and a lot of responsibility for the lads to take on board, but they’ve done that brilliantly.
“The key for us, though, is to keep winning. We’ve had four games at home, won two of them, drawn two and want to improve our record at Fratton Park.
“Lincoln have enjoyed a really good start to the season themselves and we know we’ll have to be at our best to beat them.”
There were several players missing for the midweek match at Oakwell and Mousinho provided an update.
He said: “Connor Ogilvie picked up a groin strain on Tuesday and we’ll see how he is once he gets back out on the grass.
“It’s a similar story for Christian Saydee and we’re trying to build him back up – we want to make sure he’s back at full tilt.
“Sean Raggett has trained again and was absolutely fine after getting a knock on his foot, so he’ll be available.
“The longer-term ones are all coming along nicely, with Kusini Yengi and Anthony Scully both back out on the grass, although Tom Lowery is still a couple of weeks away from that.”
