Shearer, who scored 260 English Premier League goals during his career, is an ambassador for the fitness chain which has bought into Newlife Fitness Club Ltd.
Speaking to the Leader at the opening, Mr. Shearer praised the franchise’s all-inclusive approach to physical activity.
He said: “Because of problems with my knees and ankles and back I really struggle to do high intensity exercise.
“The type of workout you get from Speedflex is the only thing I can do with no pain whatsoever, If I went to the gym to do weights like everyone else I’d be in agony the following day.
“This is 100% pain free and that’s one of the huge benefits of it.
“It’s high intensity training that and 18 year old can use in the same class as a 75 year old, all shapes and sizes can benefit, it just works.”
“Speedflex is amongst the very best, we don’t doubt it because we know it works.”
The ‘Match of the Day’ pundit also spoke about his first visit to Laurencekirk.
“This is the first time I’ve been here, I flew in this morning, I’m here for a few hours then I fly back down to the North of England later.
“The location of the gym is fantastic, there’s not many rooms you can exercise in that have the kind of view as this one.
“I’m very impressed with the area, it’s fantastic and I’ll definitely be back here soon.
“I’m up in Scotland quite a bit, I love my golf, so I try to get around as many places in Scotland as I can.”
The gyms owner, Gary Fairweather, also spoke about the benefits of the new speedflex facilities.
“Speedflex have invested some money and put in a studio.
“Now our members can get free health assessments and the use of Speedflex, which is a great thing as we are the only speedflex gym in Scotland.
“When we first signed up with Speedflex I knew Alan was involved so I asked the owner if it would be possible to get him up.
“They asked if, with him being English, would he have a big pull in Scotland and I said of course, he’s a legend, and they said they would organise to get him up here.
“We were a very small business who only advertised through Facebook before.
“Speedflex have a lot more financial power and they’ve got bigger pull, it’s a brand and we’re now part of bigger business.”
Mr Fairweather also said that despite his status as the only Speedflex gym in Scotland, he would like to see the franchise spread across the country.
“I want as many Speedflex facilities opened around the UK as possible.
“We’re hoping that if this one takes off we can get one up in Aberdeen, one in Dundee, really all the major cities in Scotland.”
Memberships for the gym have remained the same and Speedflex sessions are priced at £12 although the programme will be eventually be added to memberships moving forward.
