Hold a kettlebell or dumbbell (at a weight that gives you adequate resistance) in your right hand, and lift your left foot slightly off the ground.
Keeping your back neutral, hinge at the hip by leaning your entire torso forward while raising your left leg, which should stay in line with your body.
As the kettlebell lowers toward the ground, try to avoid swinging it, and keep the movement as controlled as possible.
With your back straight, return upright, returning to your starting position. This completes one rep. Maximise this move by keeping your right foot off the ground as you go through your reps.
