Reps: 10 per side
How to do it: Hold kettlebell in left hand. Shift weight onto your right foot. Slightly bend right knee and hinge forward at your hips. Keeping glutes and core engaged, kick left leg back as your torso comes parallel with the floor.
Press foot into the floor as you return to standing. Make sure to keep chest lifted and never round your back. Do 10 reps per side.
