What muscle work in jumping jacks?

Jumping jacks are a full-body exercise that works several major muscle groups. Here are some of the muscles that are activated during jumping jacks:

Deltoids: The deltoids are the muscles of the shoulder. They are used to raise the arms overhead and to the side.

Pectorals: The pectorals are the muscles of the chest. They help bring the arms together in front of the body.

Trapezius: The trapezius is a large muscle that extends from the base of the skull to the middle of the back. It helps support the head and neck and is used to shrug the shoulders.

Biceps: The biceps are the muscles on the front of the upper arm. They help bend the elbow.

Triceps: The triceps are the muscles on the back of the upper arm. They help straighten the elbow.

Quadriceps: The quadriceps are the muscles on the front of the thighs. They help straighten the legs and are used to jump.

Hamstrings: The hamstrings are the muscles on the back of the thighs. They help bend the knees.

Calves: The calves are the muscles on the back of the lower leg. They help point the toes and lift the heels.

Abdominals: The abdominals are the muscles of the stomach. They help keep the body stable and are used to generate power for jumping.

Overall, jumping jacks are an effective bodyweight exercise that engages multiple muscle groups, helping to improve cardiovascular fitness, strength, and coordination.
