Presente: Yo estudio Español cada día. (I study spanish every day)
Presente progresivo: Estoy estudiando Español cada día. ( I am studying spanish every day)
The main differences between the two tenses are that the present progressive has the addition of estar (conjugated) and the -ando and -iendo ending to each AR and ER/ IR verb. In English it translates as "I am" doing something; example: Estoy hablando, I am talking.
