In this months issue of the Journal of Strength and Conditioning Research (JSCR) a study entitled “Influence of moderately intense resistance training on flexibility in young sedentary women” by Elisa Santos peaked my interest.
During the study they looked at the effect of 8 weeks of strength training on various flexibility measures in young sedentary women (n=24). They split them into 3 groups alternated strength group (upper and lower alternating/n=8), anta

They tested 1RM bench press and 8 different flexibility measures at base line and then 8 weeks after the intervention. All weight training was carried out on machine weights and used multiple sets of 10-12 reps. For trunk exercises 15-20 reps was used.
After 8 weeks of training the following results where produced:
