Grease the groove: building strength with frequent, easy sets

Doing many submaximal sets spread across the day can rapidly raise your numbers on moves like pull-ups and push-ups.

Grease the groove is a method of training a single movement many times throughout the day using sets that are well short of failure. A typical version for pull-ups is doing a set of about half your maximum reps every hour or two whenever you pass a bar, for example five sets of four if your best is eight. Because each set is easy, fatigue stays low, and the goal is not to exhaust the muscles but to practice the movement so often that the nervous system becomes more efficient at producing it.

The idea relies on the fact that strength is partly a skill. Frequent, high-quality repetitions improve coordination between muscles, the timing of muscle activation and confidence in the movement. For bodyweight exercises where people struggle to get more than a handful of reps, such as pull-ups, dips, push-ups or pistol squats, this frequent practice can raise rep maximums noticeably within a few weeks. It is less suited to heavy barbell lifts, which require more warm-up and recovery between efforts.

To use it, pick one or two exercises, keep every set at roughly 40 to 60 percent of your current maximum, and stop each set with clean form and plenty left in reserve. Spread the sets across the day and take one or two days off per week. Test your maximum every couple of weeks and adjust the set size accordingly. If joints start to ache or performance drops, reduce the frequency, since the method only works when each set leaves you feeling fresh.
