forward standing barbell twist, you can either attempt to tone your
mid-section and obliques or build explosive rotational power with the standing
side barbell twist. This version of the barbell twist involves starting with the
one barbell off to the side and the other end resting in your hands, with a
close, alternating grip across your hips.
From the starting position you must rotate your arms in the path guided
by the barbell under the resistance of the barbell and any attached weight
plates. If your goal is to tone and strengthen the obliques and the
mid-section you should keep your hips as stable as possible while you turn
your shoulders only. If explosive power is what you're after you can assume
more of an athletic stance and allow the natural movement throughout your
entire kinetic chain transferring the energy from your feet all the way
through your body primarily with your obliques.
