I was a seven-stone weakling.

The speaker describes themself as extremely underweight and physically frail: “seven stone” is a British/Irish weight measure (7 st ≈ 98 lb / 44.5 kg), and “weakling” underscores vulnerability or lack of strength. In many memoiristic or testimonial contexts, such a line functions as a before-and-after marker—establishing a baseline of hardship, illness, poverty, or youthful insecurity prior to later transformation (training, recovery, maturation, or self-assertion). The blunt self-labeling also conveys shame or self-critique, suggesting the quote’s emotional force lies less in the number than in the remembered feeling of inadequacy.
