It's a simple enough apparatus that you could probably make one yourself.All it would take is a length of 1.5 in. diameter pipe from the hardware store. Purchase some spring clamps/collars for standard-sized dumb bells (you can usually find these sold in pairs in the exercise department at sporting goods stores). Load on your standard plates as in the illustrations, and you're set. Page 45 (type 49 into the page field box for quick access) of this Bob Hoffman manuscript describes several techniques using the swing bell: http://www.scribd.com/doc/50891871/40/COURSE-No-13-SWING-BELL-COURSE
vince gironda says never works abs u fool!!!!
no he did but recommended beginners do not if they are a thin underweight bodybuilder because he believed it would put their system in a state of shock and prevent normal muscle gains .. see "The wild physique" by Vince page 58.
A glance through my post history will reveal that I am a HUGE Gironda mark, but I willingly concede that he didn't know everything, and some if his ideas - especially some of the more radical ones - are maybe a bit off the mark; duplicating the effects of anabolic steroids through increased dietary cholesterol and use of glandulars, for instance.As for abstaining from direct ab work, I've personally never noticed any measurable effect, but that's not to say that nobody will.
