It's a good lift. It is also a large cappuccino, yet the episode is the only evidence which betrays her as one of Scotland's premier female powerlifters. The 42-year-old residential childcare worker from Dumfries does not at first measure up to the expectation of a flexing athlete capable of completing a deadlift of 142.5 kilograms to win her category in June's British Championships. All with more than a grunt of indignation. "When I go to lift I'm like a completely different person; I'm like an ogre," says Davidson.
That would have to be seen to be believed, although any such invitation is likely to be met with relish. Her stature belies her place in powerlifting but Davidson is every inch the competitor; she followed a second-place finish in the Scottish Championships in April by being named among a six-strong team - comprising Louise Murray, Michelle Brand, Bernie McGurk, Robert Love and Daniel Marmander - to represent Scotland at the 4 Nations in Belfast on Saturday.
Her selection was down to her prowess in lifting but it was also informed by the determination to raise her game when she chose to end a sabbatical from the sport in March. The recurring back injuries which are borne by many powerlifters, in tandem with the demands of balancing training with motherhood, had caused the Scot to take a step back. Davidson has also been diagnosed with fibromyalgia: a chronic condition affecting mostly women and which is characterised by fatigue, stiffness and widespread pain. Her grip on the sport was only ever loosened, though, and a short career as a referee proved more restrictive than the leotard and weight-belt she had chosen to stow away.
"I started refereeing about two years ago . . . I couldn't sit in that chair. I could not sit in that chair," says Davidson, who is based at Burns Gym in Dumfries. "I've been back for about five months and I'm better now than I ever was before. Everybody was asking me 'why do you want to go back to that? It's not good for you, blah de blah de blah . . . whatever'. I've also been diagnosed with fibromyalgia, which basically makes me really tired and really sore. You can't get rid of it but I just train round about it. I completely want to succeed.
"I started training again in March, started competing again and won the British. It came back just like that. When I started again I gave benchpressing a wee bash and thought 'this is not bad', but I wasn't sure if I'd be able to squat the same. But I did and at the gym we just kept putting more and more weight on."
Davidson has come to terms with competition quickly but the uninitiated will perhaps still require a moment. A contest is decided over three disciplines: the squat, in which the weights are lifted from the shoulders via a squatting motion; the benchpress, when competitors lie down and lift from the chest; and the deadlift, when a weight is lifted from the floor. "It's like what they do on Strongest Man, only when you look at their bodyweight compared to what they're lifting it's not as impressive . . . I would never say that to them, though," says Davidson.
And yet it was a bent for doing the unexpected which led her to pick up weights in the first place. Having first dabbled in the boxing ring, Davidson resolved to square up to television's Gladiators, making the shortlist for contenders before the producers of the show trumped for somebody else - "They only wanted one Scottish woman and went for a fish farmer from Skye" - before a chance meeting with a local powerlifter brought an introduction to a more lasting experience. "I stopped her in the street after seeing her picture in the paper. I asked her if I could go along and train and it went from there," says Davidson.
It could yet carry her to Plzen, where the European World Masters will be held next year. Having restricted herself to just 1000 calories a day in order to maintain her weight for the 4 Nations, reaching such a tournament will demand physical sacrifice. That is exacerbated further since her relative success has not yet built up the fiscal muscle required to compete abroad regularly.
"I was picked to represent Great Britain at the Europeans [in Blanquefort, France], but that was going to cost about £800," she says. "I am looking for sponsors and you can apply for a grant from the local sports council. I could get maybe 25% of travel costs paid for, but that is dependent on who else applies and that sort of thing."
For now, then, that is just another burden for Davidson to lift.
