Blocked Practice: Repeating One Skill Before Moving On
Quick Intro
Blocked practice means repeating the same skill many times in a row before switching to another. Hitting 30 forehands in a row and then 30 backhands, or doing 10 sets of the same kettlebell swing, are examples. It is the most common structure for practice in gyms and sports clubs.
The Idea in Plain Terms
Repetition has an obvious logic. Doing the same thing again and again lets you notice what you did, correct it and try again right away. The feedback loop is tight, so people see fast improvement within the session, which feels productive.
Blocked practice has benefits in the early stages of learning:
- Quick progress. Performance improves visibly during practice.
- Low confusion. The learner does not have to switch between tasks.
- Technique focus. Attention goes to one movement and its details.
It also has a known limit. When the same movement is repeated back to back, the learner can use the previous attempt as a template and make small adjustments each time. This lowers the thinking needed on each attempt. Performance during practice looks good, and the learning may not last or transfer to situations where the skill has to be chosen and recalled from scratch.
Researchers describe this as a gap between performance, what you do in the moment, and learning, what stays with you later. Blocked practice often produces a larger gain in performance than learning, whereas random practice, described in its own article, often shows the reverse.
A Worked Example
A beginner learning the kettlebell swing, the goblet squat and the deadlift in one session might practice in blocks:
| Block | Work |
|---|---|
| 1 | 5 sets of 6 kettlebell swings |
| 2 | 5 sets of 6 goblet squats |
| 3 | 5 sets of 6 deadlifts |
Each block focuses on one movement until the pattern is comfortable.
What the Research Shows
A line of research on the contextual interference effect, starting with Shea and Morgan in 1979, compared blocked and random practice. In many laboratory studies, blocked groups performed better during practice, and random groups performed better on later retention and transfer tests. A 2004 meta-analysis by Brady confirmed a benefit of higher interference on retention in many studies, with variation by task and learner.
Skill level matters. For beginners, and for very complex skills, blocked practice often works well early on, because the learner has not yet formed a basic movement pattern. The challenge point framework proposed by Guadagnoli and Lee in 2004 suggests that the best level of difficulty depends on the learner’s skill and the task, so a beginner needs less challenge than an expert.
A reasonable reading is that blocked practice is useful for first exposure, and later practice benefits from mixing tasks.
Who It Suits
- Beginners meeting a new movement.
- People refining one specific technique fault.
- Settings with limited time or equipment.
It suits experienced learners less, who gain more from mixing skills.
How to Use It
- Use blocked practice at first exposure to a new movement.
- Keep sets short enough to maintain quality.
- Move to mixed order once the pattern is stable.
- Take regular feedback from a coach, mirror or video.
- Avoid drilling a faulty pattern. Stop and fix it.
- Return to blocks when you change a technique detail.
Common Misunderstandings
It is not bad practice. It has a stage where it fits.
It is not the same as lifting sets of the same exercise for strength.
It is not enough alone for skills used in unpredictable situations.
FAQ
Why does it feel more productive? Performance rises quickly within the session.
When should I stop blocking? When the basic movement is consistent.
Is it good for sports skills? At first. Later, mixed practice transfers better.
Does it apply to lifting? For technique learning, yes.
