Well, I just saw something I thought I would never observe–a new exercise from, of all places, the TV Guide Channel. It actually looks like it might be useful, although I really hate to say that, so my personal jury remains out until I try it myself. The world must be ending.
Anyway, the exercise is a variation of the woodchopper, done using a long straight rowing bar with a cable attachment, but on the end of the bar instead of in the middle. You attach it to a low pulley and hold and swing it like an axe or sledgehammer. The bar looks to be a regular cable bar, although I didn’t get more than a glimpse. Just an FYI. I may try it my next workout, see if I can jury-rig an imitation.
