The Blues partook in a full session of strength and conditioning training at Cobham headquarters on Wednesday afternoon, complete with giant Swiss balls, resistance harnesses and medicine balls.
Conte then warned his players at the start of this season not to let their standards slip to the levels of "the last season with Mourinho".
In the build-up to the highly-anticipated clash, Cahill pointed out that Lukaku, who is a former Chelsea player, will be a handful on the day. "We have another chance to play in another final against a top team". In this instance, Andreas Christensen and Ross Barkley had to try and jump and head a ball while Cesar Azpilicueta and Danny Drinkwater held them back.
"There are positives to take from that game", Jones said.
In the last season's FA Cup, Chelsea had eliminated Manchester United in the semi-finals by a 1-0 victory.
United's progress under Mourinho has been impressive this season and they garnered 12 more points in the Premier League than they did in his first season.
Speaking to reporters on Monday, he said: 'For the next game, for sure we must change.
Forget about that couple getting married because Saturday afternoon is for the FA Cup final. You enter every competition trying to win it, and we fell short in the other competitions but we've not fallen short in this one yet.
"Maybe if we'd won comfortably at Newcastle we'd go in with momentum, or maybe we'd go in a bit more relaxed thinking we're in good form".
He continued: "We know we have Man United in the final, but it won't be easy".
Conte and Jose Mourinho's tempestuous relationship means there will be plenty of focus on the dugouts this weekend, although Moses feels he has nothing to prove to a manager who did not give him the chances to shine granted by his current boss.
"They've got some very strong players and he's used to winning this competition".
