Stand tall, feet hip-width apart. Shift weight to your right foot, engaging it firmly. Hinge at the hips, extending arms forward and lifting your left leg straight back, forming a horizontal line. Maintain a slight bend in your standing knee. Focus your gaze on a point ahead to stabilize. Hold for 5-10 breaths, actively engaging your lifted leg's glutes. Slowly lower the leg and repeat on the opposite side.
Engage your standing leg with a slight bend for stability. Engage your glutes and hamstrings by pressing your heel down. Focus your gaze on a fixed point to maintain balance. Reach forward and lengthen your spine.
