South Africa is in the midst of a 21-day nationwide lockdown, which prohibits leaving home except to buy food or medicine and does not allow for any outdoor exercise.
CSA's focus now is on maintaining the players' fitness and trainer Tumi Masekela has sent all the players their training programmes.
"We've got time now to work with players in terms of addressing the small niggles that they may have. They have got time to rest and also to do the strength work," he said.
"But the one big thing is the running volume, the aerobic capacity base, which I am going to try and build up in the next two weeks, so that means lot of running, or a lot of cardio work, cycling or swimming."
The South African team doesn't have any international match lined up until June.
