Johannesburg: With less than two weeks to go for the India tour to begin, South African bowlers have stepped up the gas in a preparatory camp under bowling coach Charl Langeveldt.

The Proteas bowlers today took part in a thorough session under the watchful eyes of Langeveldt with the aim of increasing their workloads and mapping out expectations and game plans ahead of the 72-day tour which starts with the first T20 in Dharamsala on October 2.
