The goblet squat hold is literally holding a kettle bell in the bottom of a squat. This is an isometric hold which is super effective at improving hip flexibility. You want to use a moderately heavy weight. Flip the kettle bell upside down and hold it by the belly of the bell, or the part that would resemble a goblet. Lower into the bottom of the squat with the elbows just inside the knees. Use your elbows to drive your knees outward increasing the stretch on the adductors. Hold this stretch for 10 deep inhales and exhales.
This is a great stretch for the hips, hamstrings, and glutes, while also strengthening them as well. It also targets the hip flexors and stretches the groin.
