The Claim

A one-week complete cessation of resistance training during a 9-week high-volume program reduces subjective readiness to train in young, resistance-trained adults, as indicated by increased muscle soreness and decreased motivation compared to continuous training.

Cause and effect
1 study reviewed
In plain English

Young adults who stop resistance training for one week during a nine-week high-volume program experience lower motivation and higher muscle soreness than those who train continuously, resulting in reduced subjective readiness to train.

See the scientific wording

A one-week complete cessation of resistance training during a 9-week high-volume program may slightly reduce subjective readiness to train in young, resistance-trained adults, as the deload group reported increased muscle soreness and decreased motivation compared to the continuous training group.

Why this might work

When training stops, muscles experience more stress from everyday movements without the protective adaptation from regular lifting. This makes the muscles feel sore and tired. At the same time, the brain reduces its drive to activate those muscles, making the person feel less motivated to train.

    People who took a one-week break from weight training felt less motivated and less ready to train compared to those who kept going, even though their muscles didn’t get smaller. This matches the claim that breaks can make you feel a bit more sore and less pumped to work out.
