Team NI will have four weightlifters at the Games in Glasgow, twice as many as in 2022.
Harrison McGrogan is the youngest of the four and he will compete at his first Commonwealth Games in the 71kg category.
The 18-year-old, who was previously a rugby scrum-half, claimed victory in the British Championships in the 71kg.
Omar Keshta will also compete in his first Games in Glasgow in the 110kg+ weight category.
Hannah Crymble is back for her second Games after finishing sixth in Birmingham. The 30-year-old, who balances weightlifting with her full-time job as a nurse, is a back-to-back British champion in the 63kg.
Kaitlin Saunders is preparing for her first Games after being inspired to take up weightlifting after watching the 2022 Commonwealth Games.
A former gymnast and CrossFit athlete, she lifted the qualifying standard at 77kg.
