Unfortunately, based on the provided reference material, a comprehensive guide on how to bench press at home isn't available. The snippet focuses on a specific part of the bench press technique - driving the bar up in a slight arc towards your head to boost chest muscle activation. Therefore, a full "how-to" cannot be derived. For a safe and effective bench press, especially at home, you'll need more information than just this arc movement.
Because the provided content is insufficient to answer the question in its entirety, I cannot provide a safe or complete answer. A good guide needs information on equipment, setup, proper form (beyond the limited excerpt), safety considerations, and variations. Without this information, any attempt at providing a "how-to" would be irresponsible.
