Starting position: Lie on your back with legs bent, feet flat on the ground hip-width apart. Hold a dumbbell in each hand, crossed over your chest—keep them stationary throughout.
Movement: Exhale as you lift your head and upper back. Inhale to lower slowly without letting your shoulders or head rest fully. Perform 10-15 reps, 4 sets.
Coach's tip: "Control the movement by slowly rolling and unrolling your neck and back."
Starting position: Lie on a bench or ottoman with knees bent, feet flat. Extend arms vertically overhead, one dumbbell per hand, palms facing each other.
Movement: Inhale to lower the left dumbbell toward your forehead a few centimeters. Exhale to extend the left arm while simultaneously lowering the right—alternate. Do 30-50 reps, 4 sets.
Coach's tip: "Keep only your forearms moving; elbows stay fixed. Press your lower back firmly into the bench."
Starting position: Lie on your back with legs straight, heels on the edge of a sofa or bed, hip-width apart. Rest dumbbells on your lower abdomen, one per hand.
Movement: Inhale to lift your pelvis, squeezing glutes hard. At the top (thighs aligned with torso), exhale to lower. 15-20 reps, 4 sets.
Coach's tip: "Don't fully relax glutes on the descent, or your lower back will compensate—risking injury."
Starting position: Stand with feet shoulder-width, knees slightly bent. Hinge at hips to a 45° angle, back straight. Arms hang down with dumbbells, palms facing each other; head aligned with spine.
Movement: Raise slightly bent arms to shoulder height without moving your back, then lower. 10-15 reps, 4 sets.
Coach's tip: "Master the form without weights first. Avoid jerky motions—your back is vulnerable here."
