John Barrows, one of the most respected sales trainers in B2B, makes a compelling case that practice is the most underleveraged competitive advantage in sales --- and the one thing most reps consistently skip. In this concise, high-impact video, Barrows draws parallels between sales and professional sports, pointing out that no athlete would show up to a game without practice, yet most salespeople step into high-stakes calls completely cold. He breaks down what deliberate sales practice actually looks like: role-playing objections, rehearsing value propositions out loud, and drilling discovery questions until they become muscle memory. Barrows is candid about the discomfort that comes with practice --- nobody likes hearing their own voice or stumbling through role-plays --- but he argues that the reps who push through that discomfort are the ones who consistently hit quota. He also shares practical tips for integrating practice into a busy schedule, including micro-sessions between meetings and team-based practice rhythms that don't require hours of blocked time.
