I shall pose a question here..but before I do, Breathe I use as pole dancing display ( to many sniggers..c'mon, it's done to fit the music).
In my own way, and we shall hope that people cross train,as opposed to BP only to achieve their goals. The average person in this day and age needs to lengthen their calf muscles as opposed to shorten them.
BP is a workout,and it has been said before on this thread, that your calves are used as stabilisers in the majority of tracks.
If you were/are either attending BA/BC/RPM/BS or any freestyle versions of these, your calves are getting worked.
If you run,on the road or a treadmill,or even walk, to increase your cardio(again, cross training), there is no specific need for BP to provide a "calf" workout.
I would hope that the majrity of people out there would participate in some way,shape or form, another exercise discipline.
Just my thoughts.Let's not get into a Mike vs Glen debate please.
