The Köhler effect is a phenomenon in which people in a team or group perform better when surrounded by more competent people. This was demonstrated in a study published in the Journal of Sport and Exercise Psychology, in which participants were asked to perform a series of planks independently and with a partner. The results showed that partner work helped the participants hold their planks for longer than when they were on their own. And participants who exercised with a ‘more capable partner’ increased their plank hold time by 24%.This phenomenon can be used to improve your workout results by buddy-ing up with someone who is more fit than you. This will help to motivate you and also improve your mobility and movement patterns.
