Kelly Lee is taking you Back to the Basics of Strength Training. If you're following the series, this is the eighth workout of the program, where you'll continue to build strength and endurance, but move towards a focus on the core. Kelly is going to show you moves like rockettes that will tone those trouble spots like the lower abs and obliques. Just because you're giving your arms and legs a rest, doesn't mean this class won't be challenging, so bring your A game.
