Criss-Cross Arm Lift

1. Stand with your feet shoulder-width apart and your arms extended to the sides at shoulder height, palms facing down.

2. Cross your arms in front of you at about chest height with your right arm over your left.

3. Open your arms back out to the sides, returning to the starting position.

4. Now cross your arms with your left arm over your right.

5. Again, open your arms back to the sides.

6. Raise your arms straight above your head, keeping your elbows straight.

7. Lower your arms to return to the starting position at shoulder height.

8. Repeat the sequence for the desired number of repetitions, alternating the cross of your arms with each repetition.

This exercise engages the muscles in the shoulders and upper back, with secondary activation in the chest and arms. It's a bodyweight movement that can serve as a warm-up exercise or be included in a bodyweight strength routine, focusing on endurance and muscle tone.
