this amusing term originated from Stefan Siikavaara, IFFF-MCCI from Sweden in reference to a casting demo i did for the group of instructors at fly casting gathering a few years back.
the idea is if we relax some of our muscle groups instead of tightening up as is so common, we’re more fluid and in better control when we move. we’ll be able to better use other muscle groups, we’ll bend, twist and straighten better, all the while being smoother and more precise in the way we move our whole body.
this leads to not only performing better but this also reduces the possibility of cramping up and injuries from over-exhertion and repetitive motions.
anyway, the SRB thing is quite simply relaxing the butt muscles combined with a slight flexion of the knees. doing these two things loosens up the whole back and legs and it really helps most people to stay consistent in their casting. as a side bonus, this tends to relax the shoulders, neck and mind as well. combine this with stretching and conscious controlled breathing and we’re good to go in peak condition.
a non-negligable effect to explaining this to a group is of course the giggles and goofy comments that arise, all working towards even more relaxation of the attendants.
the butt muscles are our biggest muscle group and it’s a place where a lot of us gather a lot of tension resulting in back/leg stiffness. take that tension away and we become like swaying, dancing springs. springs ready to jump into action !
get up and try it right now. i’m sure you’ll feel the difference.
