But when she slips into a bikini Ronnie is seriously hot property herself as one of the UK's finest figure and bikini competitors.
University graduate and female bodybuilder Ronnie has been competing for 12 years and she continues to go, literally, from strength to strength.
Her 5ft 9ins, 135lbs, muscular physique is tailor-made for figure and bikini and those elegantly muscled legs are among the best in the sport.
A six-days-a-week training regime has carved her a contest-winning look which combines serious muscle (particularly her terrific abs) with serious curves. And all this is packaged with a healthy sprinkling of real superstar glamour.
Now aged 35 Ronnie Blewitt is prepping for her seventh bodybuilding show (she won't tell us which one yet!) and she has never looked better.
The Kent-based figure star said: “The contest is still 'TBA' but my goal at the moment is definitely to get stronger.
“The thing I love about bodybuilding is that it is a never ending pursuit. And the thing I hate about bodybuilding is that it is a never ending pursuit!”
Ronnie, who speaks three languages, is a former British Figure Champion and was the first UK figure girl to win the British titles in both the biggest natural federation AND non-natural federation.
She has appeared in many muscle mags and womens magazines including Muscle and Fitness, Flex, Bodyfitness, Hello, OK, Bella, B Magazine, and Health & Fitness.
She has also made TV appearances on legendary UK daytime TV show Richard and Judy as well as Discovery Health (Body Idol) and Transworld Sport
