Seal Jacks

Introduction: Seal jacks are a dynamic exercise similar to traditional jumping jacks, but with a focus on opening and closing the arms in front of your chest. This exercise is excellent for improving your coordination and raising your heart rate.

Execution: Start with your feet together and your arms at your sides. Jump your legs apart while simultaneously bringing your arms in front of your chest and clapping your hands together. Jump back to the starting position while bringing your arms back to your sides. Repeat this movement at a smooth pace.

Key Muscles: Seal jacks primarily train your shoulders, chest muscles, and upper back muscles. They also work your leg muscles and core stability.

Benefits: This exercise not only helps improve your cardiovascular fitness, but also strengthens the muscles involved in opening and closing your arms, contributing to better posture and shoulder stability.

Common Mistakes: A common mistake is not fully extending the arms or not clapping the hands properly in front of the chest. Make sure your arms are fully extended and that you clap firmly to get the most out of the exercise.

Possible Alternatives: To increase the intensity, you can hold a light dumbbell in each hand during the exercise. For a less intense variation, you can replace the jumps with steps.
