Weightlifting might look like it is all about brute strength, but technique and concentration are also vital.

The aim of the game is simple - to lift more weight than anyone else.

The Olympics and Commonwealth Games competitions are divided up into weight categories.

This also includes powerlifting for elite athletes with a disability (EAD).

There are two main types of lifting technique: the snatch and the clean and jerk.

In both categories, competitors are given three attempts to complete a lift.

Once lifters reach the platform, they have one minute to attempt the lift. If they are successful, their next attempt must be at least 1kg heavier.

The heaviest successful lift in each category contributes towards the total score, so if an athlete lifts 90 kg in the snatch and 130kg in the clean and jerk, their overall score is 220kg.

In EAD powerlifting, athletes compete lying on their back and must complete a successful bench press within two minutes.
