A 74-year-old fitness model who lost over 62lb (over four stone) three years ago has become an Instagram sensation – and now teaches workouts to over 800,000 followers.
Joan MacDonald, from Cobourg, Canada, who tipped the scales at 198lbs (14st 1lb), was on medication for high blood pressure and was struggling with with such severe arthritis she struggled to walk up and down her stairs.
Determined to make a change, the mother began weight training and planning her macros, eating five balanced meals a day – amounting to around 1500 calories in total.
She now weighs a slender 136lbs (9st 7lbs) and has amassed thousands of followers by sharing her weight loss journey through her Train With Joan Instagram account.
