Agustiani lifted 85 kilograms in the snatch and 107 in the clean and jerk while Hiromi had attempts of 81 and 107 in the snatch and clean and jerk respectively.

With the leading pack seemig to increasingly going out of reach, Chanu went for 106 kilograms in her remaing two attempts, but could not register a single successful lift, thus crashing out of contention.
