Does daily sales practice work? What the research says.
Short, frequent practice beats one big training day. Here's the evidence, and what it means for a sales floor.
pooled in one review. Overall, practice spread out over time beat the same practice crammed into one session.

CSO Insights sales coaching researchThree findings that matter on a sales floor.
The largest review of spaced practice pooled 839 results from 317 experiments in 184 articles. Practice spread across sessions was remembered better than the same practice done all at once.
Cepeda, Pashler, Vul, Wixted & Rohrer (2006)In a field study of 64 bank employees, one group got sales training in spaced sessions and the other got it all at once. The spaced group applied the skills better on the job, rated their own sales ability higher, and improved their sales figures.
Kauffeld & Lehmann-Willenbrock, Journal of European Industrial Training (2010)People who practiced recalling material, instead of re-reading it, remembered much more of it days later. For reps, that means saying the answer to an objection out loud beats re-reading the script.
Roediger & Karpicke, Psychological Science (2006)Companies with a formal coaching process reported higher win rates (53.6%) than those that coached informally (45.7%) or only when managers had time (44.7%).
CSO Insights sales coaching studyA little every day beats a lot once a quarter.
None of these studies tested an exact number of minutes, and we won't pretend they did. What they agree on: practice that is short, frequent and out loud sticks, and one-off training days fade.
That's why we recommend a 10-minute habit: before the first call block, each rep practices the objection they get stuck on most, out loud, against a prospect who pushes back, and gets feedback right away.
Della Practice is built for exactly that: an AI prospect your reps call by voice, using your real objections, with a grade after every call. Try a free call →

Common questions.
How long should sales reps practice each day?
No study has tested an exact number of minutes. The research shows that short, frequent practice beats one long training session, so a short daily habit, such as 10 minutes before the first call block, fits what the studies found.
Does role-play improve sales results?
In a field study of 64 bank sales employees, the group that practiced in spaced sessions applied their skills better and improved their sales figures compared with a group trained all at once (Kauffeld & Lehmann-Willenbrock, 2010).
What is the most effective way to train salespeople?
Spread practice out over time, practice out loud instead of re-reading scripts, and get feedback right after each attempt. Spaced practice and retrieval practice are two of the best-supported findings in learning research.
How can I improve my sales?
Find the objections you lose calls on most, practice your answers to them out loud a little every day, and review your calls for what worked. Companies with a formal coaching process reported higher win rates (53.6%) than those that coached informally (45.7%).
