[Standing one-arm overhead press] mainly exercises the strength of the shoulders, triceps, waist and abdomen. With your feet spread apart, place the dumbbell at shoulder level, palms facing forward, and wrap your arms around the dumbbell handles. Inhale deeply and tighten your core to maintain the natural curvature of your lower back spine. Bend the knees slightly and push the dumbbell upwards to the head position. Pause at the top of the movement, then lower the dumbbells back to the starting position. After doing 6 to 12 times on one side, switch to the other side.
