Box lift and place is a better assessment than pushups and chinups for job strength tasks

Current generic fitness assessments (including push-ups, sit-ups and chin-ups) are often poor predictors of performance in strength based job tasks. In a DSTO study involving over 100 soldiers, the effectiveness of push-ups, sit-ups and chin-ups was compared to a ‘box lift and place’ assessment method (pictured) that involves lifting a weighted box in a manner …
