The actress gave birth to daughter Nahla on 16 March, with partner Gabriel Aubry by her side.
But insiders say she's keen to get her figure back in time for the Halle Berry Celebrity Golf Classic on 27 April.
'She wants to be back in fit form for the tournament,' a source tells Us Weekly.
'She's thrilled to start exercising again.'
Halle, 41, has been using yoga, swimming and light weights to get back in shape. And she's even been brushing up on her golfing skills.
The weekend-long event is in aid of the Jenesse Center, which helps abused women and children.
