Ms Melissa Ong found out last year that she had osteopenia - early signs of bone loss that can develop into osteoporosis. So, her doctor encouraged her to lift weights to build up her bone density.
She hired a personal trainer who taught her basic lifting skills that included the squat, benchpress and deadlift - the three powerlifting moves.
At the start, she could not even do a bodyweight squat. But that did not stop her.
She got stronger eventually, and started training with a barbell and later added weights. Today, the 51.7kg woman can deadlift 65kg.
Ms Ong says: "Powerlifting has changed the way I move. It has improved my posture and balance.
Her mother, Madam Minnie Lee, 73, was starting to fall down a lot but now they work out at the gym together, including her father, with the help of a personal trainer.
Madam Lee works out with kettlebells and the Smith machine. Her husband, who used to do bodybuilding, uses weight machines and can benchpress 40kg weights.
