An old pair of tights or leggings works well in place of a resistance band.
How do we get more stability in the Core? We challenge it to remain still while we move the limbs.
We'll fire up the abs too with the series of 5 - love it or hate it, it a super effective sequence for building strength.

Enjoy!
