The 29-year-old featured in 45 games in all competitions last term – the most of his seven seasons as a Hammer – as he played a key role in the team's strong performances at home and abroad.
“I had a very good holiday with my family and friends," he said, “You need to relax – your mind, you body, everything to get to 100 per cent to work hard for the pre-season.
“But now it's good to be back, because it's great to have a holiday but part of you misses this environment. You miss the training, being around the lads, so I'm happy to be back.
The Hammers are back on the east coast of Scotland for the third consecutive pre-season and Lanzini is delighted to be on familiar turf for the first week of the preparations.
Lanzini told whufc.com: “It's a good place, the training is good because you have everything here. The weather is good too because it doesn't get too hot.
“It was a hard day on Tuesday, but this is pre-season, every day needs to be hard because if your goal is to be ready for the season, now you need to prepare for what is coming.
“I'm feeling strong and last season, personally, was really good because I played a lot of games. Now I'm focused on staying at that level to play that number of games again and help the team and the Club in the season ahead."
