Please check my answer. Are all the accent marks, grammar, and spelling correct?

¿Qué hago para ponerme en forma?

Para ponerme en forma hago ejercisios y como bien.

Or, should it be:

Para ponerte en forma haz ejercisios y come bien.

To check the accent marks, grammar, and spelling in your answer, "¿Qué hago para ponerme en forma? Para ponerme en forma hago ejercisios y como bien," we can go through it step by step:

1. Accent marks: In the question "¿Qué hago para ponerme en forma?" the accent mark in "Qué" is correct because "qué" is an interrogative pronoun. However, there should be an accent mark in "ejercisios" which should instead be "ejercicios." Similarly, "como" should have an accent mark, making it "cómo."

2. Grammar: The grammar in the question "¿Qué hago para ponerme en forma?" is correct. It translates to "What do I do to get in shape?" In your response, "Para ponerme en forma hago ejercisios y como bien," the grammar is also correct. It means "To get in shape, I do exercises and eat well."

3. Spelling: As mentioned earlier, "ejercisios" should be "ejercicios," and "como" should be "cómo."

After applying these corrections, the updated sentence would be:
¿Qué hago para ponerme en forma? Para ponerme en forma hago ejercicios y como bien.

Please note that the correct spelling may vary depending on the country or region where Spanish is spoken, but the general rules mentioned above should apply.
