It's easy to do a bridge with your knees bent, but when the lever arms are larger, it asks a bit more of your hip extensors and abs. Use a light load overhead (10-20 pounds works just fine for big guys) and gun for reps on either side.

Use all the cues you've put into practice from your Turkish get-ups, deadlifts, pull-throughs, and other movements and apply them here, bracing the trunk, engaging the glutes and hamstrings, and achieving full hip extension on each raise.
