Resistance training increases flexibility and speed along with power.Hi I have been boxing as an amateur for a few years now. I am currently 6'1" and 75KG. Is it possible for me to gain above 85KG doing Heavy resistance training without sacrificing my flexibility and speed as a boxer?
No, weight lifting and resistance training are two different things: weight lifting with weights; resistance training with rubber tubing, therabands, and etc. which has been proved to increase muscular flexibility, strength, and speed. I lift with therabands all of the time and I know first hand that it works.do you mean resistance as in weights? A lot of people say that decreases speed and flexibility. I agree because since i quit lifting weights ive gotten faster.
