hi Pooja...walk for 30min...rest for while then again to walking..walk slowly.enjoy your walk..be happy

30 min is ok if not in one go than take breaks nd not too fast just normal walk , listen to ur body nd don't over do . all d best dear keep health nd happy

Start from 20 min normal walks in starting n thn slowly increase ur speed but not like jog a brisk walk to half an hour morning.. Evenin wth exercises as per your gyanac suggestion..
