The prevalence of injuries resulting from improper weight training technique among recreational lifters is of serious concern. Recreational lifters often receive limited instruction regarding safe practices. Four exercises, the latissimus dorsi pulldown, the bench press, the squat and the knee extension, were identified as commonly performed at risk. Writers of the sports medicine literature have suggested that these exercises have potential physiological benefit, but mat cause injury when performed incorrectly. The current study employed positive practice in order to increase safe weight lifting among 10 recreational lifters. A multiple baseline design across the four exercises was utilized to illustrate the effects of positive practice on safe weight lifting. Positive practice resulted in an average increase of 46% safe for the latissumus dorsi pulldown, 70% safe for the bench press, 56% safe for the squat, and 60% safe for the knee extension. Social validity measures indicated that positive practice was an acceptable intervention.
