Breaks and detraining
Stopping training for a few weeks progressively reduces strength and power; short breaks carry little cost, and what is lost returns once training resumes.
Meta-analysis · 1 source · 2 min
What the studies show
- Maximal strength dropped little during the first weeks of the break and more noticeably after a month.
- Power and stretch-shortening cycle performance were more sensitive to the break.
- Resuming training restores performance faster than building it from scratch.
How Letz applies it
After a logged break, the coach reduces load and volume for the first week instead of picking up right where you left off.
Who it applies to
Trained adults who take a break from training for weeks.
Limits
The rate of loss varies by age, training level, and type of capacity; it does not measure what happens during illness or injury.

More in Training
- Resistance Training, Strength, and HypertrophyVarious training prescriptions improve strength and hypertrophy; heavier loads favor strength, and multiple sets favor hypertrophy.
- Weekly Volume: Sets per Muscle GroupMore weekly sets per muscle produce greater hypertrophy, with diminishing returns; for strength, moderate volumes already capture most of the gains.
- Frequency: training each muscle at least twice per weekTraining a muscle group twice a week is superior to once for hypertrophy; for strength, higher frequency helps primarily because it distributes volume more effectively.
- Load and rep rangeLight and heavy loads produce similar hypertrophy when sets are taken close to failure; heavy loads are superior for maximizing strength gains.
