Because she knows about fitness and she's also a sports person so i thought , if you are sports person and gym trainer too so this combination helps us make our body good. And i knw about her journey she is on this feild still 10 to 12 years almost . And m thinking there is no bigger reason about why she was trustworthy teacher or not.
