The Reason behind this punishment is YOGA. Sit Ups are part of Super Brain Yoga. It improves memory power.
It is not just a form of punishment in classroom but also traditional practice for many who perform it while offering prayers. i.e Devotees pray to forgive them for any mistake caused intentionally or unintentionally and punish themselves through this process and is hence a common scene in temples in South India.
