Re: Swiss Ball GHD
I've been using a swiss ball and anchoring my feet against the pad on a leg extension machine - the only use I've found for one so far. Takes about 5 seconds to set up, works well for back extensions, situps etc. Failing that, I lower the bar on a smith machine to a suitable height - The only good use for that also! Only downside with a ball I always have to do some arranging of anatomy however, to avoid a mid-set debilatating mishap.
