I've read the "useless exercises" sticky, but I'd like for us to fish in our memories. I haven't seen it since the late 1960's, but "the bicycle" used to be a common exercise. You propped yourself up on your neck and shoulders, supported your hips with your hands, and spun your feet like you were riding an upside-down bicycle.
Besides killing your cervical vertebrae, what was this supposed to accomplish?
While we're on the subject, what about jumping jacks? They exercise what muscles, exactly? Are they cardio? Then why did the PE teacher always have us do exactly 10?
Then there's the vibrating belt across our butts...
What other exercises did we used to do, back in the day, that we now realize are laughably ineffective?


From the sound of the "new" one, I might like to try it.
