For those who feel 24 strokes with a cane is rather light:

The offender shall receive no more than 24 strokes of the cane on any one occasion, irrespective of the total number of offences committed. In other words, a man cannot be sentenced to more than 24 strokes of the cane in a single trial, but he may receive more than 24 strokes if the sentences are given out in separate trials. However, in the first case where a prisoner was received more than 24 strokes in a single trial, armed robber Qwek Kee Chong (who served ten years in prison) was given 48 strokes of the cane on 8 April 1988 and later hospitalised for his grievous injuries from the caning; he was later granted compensation for this error.

The caning officer positions himself beside the trestle. The Director of Prisons explained in a 1974 press conference, "Correct positioning is critically important. If he is too near the prisoner, the tip of the cane will fall beyond the buttocks and the force of the stroke will cause the unsupported tip to dip and bend the cane and thus reduce the effect of the stroke. If he is too far, the stroke will only cover part of the buttocks." Strokes are delivered at intervals of about 30 seconds. The caning officer is required to exert as much strength as he can muster for each stroke.

Remember, this is in addition to the prison sentence.
