Your core's main purpose is to stabilize your spine. And while holding a plank is a great way to strengthen a weak middle, the classic exercise doesn't carry over much benefit to daily movements. "Everyday tasks--like shoveling snow or reaching for your phone on your desk--twist your spine," says BJ Gaddour, C.S.C.S. and creator of 10-Minute Torchers. "If you can't properly brace against the load and momentum, you risk back injury overtime." Thats why the seesaw shredder is a great way to test real-world core stability. As the weights swing back and forth, your core muscles have to fight to resist rotation. The faster you swing, the harder your abs have to work. Add it to your weekly routine to not only increase your strength and power in everything you do, but to also sculpt every inch of your core.
DIRECTIONS
Perform the exercise for 30 seconds. Rest for 30 seconds. That's 1 round. Perform 3 more rounds. Want an even bigger challenge? Grab one dumbbell that’s slightly heavier than the other, suggests Gaddour.
