To set up, grab a pair of dumbbells. You'll be able to lift heavier weights than when you do a traditional lateral raise—but start light until you nail the form. Stand up straight and tall holding the weights, squeezing your glutes and abs to create full-body tension.

Start with four sets of six to eight reps.

The half-kneeling kettlebell windmill is a challenging abs exercise that you can do to work your core and build shoulder stability.

Three sets of six to eight reps should work, as each should take about two to three seconds to get through each rep.
