​

Purpose: To examine the strength and flexibility gains after isolated or simultaneous strength and flexibility training after 16 weeks.

​

Conclusions: Strength training may contribute to the development and maintenance of flexibility even without the inclusion of additional stretching, but strength and flexibility can be prescribed together to get optimal improvements in flexibility.

​

IN PLAIN ENGLISH: Performing proper strength training (full range of joint motion and multiple angles of exercises at the joints) can enhance joint flexibility by itself.
