Within United's Scottish training camp, Richard Cresswell is in the thick of his 19th pre-season work-out.
The 35-year-old keeps himself in good shape and is enjoying this summer's regime under new boss David Weir and the Blades coaching team.
Cresswell and his team-mates took part in a training session at Glasgow Rangers' Murray Park on Monday, building up to Wednesday's final game of the three-match tour, which is against Raith Rovers (7.30pm kick-off).
"Pre-season gets hard when you get into the 30s, especially with the young ones running about, but I look after myself physically and this pre-season has been really enjoyable," said Cresswell.
"It has been based around playing football, rather than lots of running. We've kept a high intensity and we've been working on our fitness through football and hopefully we'll see the benefits of that when the season kicks off."
Cresswell, of course, finished last season with an injury, sustained whilst on loan at York City, but says he is fully fit and raring to go.
He adds: "I'm glad I went to York and got a few games, helping them stay up. The calf strain was not nice but I'm fine now and I'm delighted that I've been able to join in every session during pre-season."
