Sundaram, who has the distinction of taking ten wickets in an innings in a Ranji Match, said bowling more and more overs in the nets is key to a fast bowlers' success.
"We used to bowl long spells. Now with number of matches increased, the bowlers are more careful and cautious about their fitness. The gyms have reduced the flexibility and the body snaps like rusted iron when it takes extra load. You certainly need strength from gym but you should also bowl more," the former paceman, who took 16 wickets in a Ranji match against Vidarbha in 1985-86 season, told PTI.
"It obviously needs strength and power but it is more about rhythm which comes naturally. But the budding pacers should realise that there is a limit to speed but skill has no limits. You should also try to develop skills of fast bowlers," Sundaram said at the training camp for the Rajasthan Ranji probables.
