The importance of a warm-up before a poker session is akin to preparing for any mental challenge. It primes cognitive functions, sharpens focus, and enhances decision-making. A brief warm-up routine, including reviewing strategy, analyzing recent plays, or even engaging in mindfulness exercises, readies the mind for the complex calculations and psychological nuances of poker. It helps to shake off distractions, establish a focused mindset, and improve overall performance, making the warm-up a valuable ritual for success at the poker table.
