Weighted down

Since nobody would throw a mild-mannered guy like Kurapica into a river to sleep with the fishes, the weights must mean he's indulging in one of the oldest cliches in anime: training while wearing weights.

I'm not completely sure but I think Goku might be able to claim credit for inventing the whole train-with-weights-then-take-them-off-mid-tournament-to-startle-the-villain thing...
