Practice a repeating circuit of blanket drills to focus strength through the lateral and spiral lines of the body, concentrating on the core. Challenge yourself with lateral slides and dynamic variations of plank, intersecting the core in innovative ways and helping to connect the hemispheres of your body. You'll need a slippery floor with a blanket or towels, but if you're on carpet you can use paper plates for most of the drills. Props Needed: Two blocks and a blanket or paper plates. Props Suggested: A yoga mat.
