Everything is rosy when you have two hands firmly on a barbell, but it can be a different story when you're forced to move unilaterally. The beautiful thing about many kettlebell movements is that they're designed to be completed one hand at a time.

This complex forces you to brace for rotation, and can absolutely smoke your core. I use this with drop sets by working up to 3 sets of 5 reps and then dropping the hardest exercise, in this case, the single-leg Romanian deadlift with a row.

Once that beast is out, I move up in weight with my 'bells while thanking the Almighty for taking mercy on me, and move on.
