A jumping jack is a fun way to move.

First, you jump your legs out wide. Then, you swing your arms up high. You can even clap your hands! Next, jump back to the start. Keep your feet close and arms at your sides.

Some people do star jumps to go higher. One man did 136 jacks in one minute. It is a great way to stay active.

A jumping jack is a way to move your body.

You start by standing straight. Then, you jump your legs out wide. At the same time, you swing your arms up high. Some people clap their hands overhead. Next, you jump back to the start. Your feet go together and your arms go down.

People call these star jumps too. The name comes from a toy called a jumping jack. That toy moves its arms and legs when you pull strings. There are many ways to do this move. You can do power jacks by landing in a wide squat. You can do half jacks by only lifting your arms halfway. Some people do star jumps to leap very high in the air.

People like to test their skill. In 2023, Binod Thapa did 136 jacks in one minute. He did this in Nepal. In 2010, a big event helped many people move. Over 300,000 people did jumping jacks in one day!

There are many ways to perform this jump. First, you jump your legs out wide. At the same time, you swing your arms up high. Sometimes, you might even clap your hands overhead.

Half jacks only lift the arms halfway up. Star jumps are even more explosive and involve jumping very high.

This exercise has a very interesting history. Some say it began in 1885 at West Point Military Academy. A man named John J. "Black Jack" Pershing may have used it. He reportedly used it to tease new students called plebes. He would make them move their arms and legs like puppets. The name does not actually come from the general, though. It comes from a children's toy called a jumping jack. That toy moves its limbs when you pull its strings.

Many people have shared this move with the world. A fitness expert named Jack LaLanne helped make it popular. He showed people how to do it on television for many years. People also use jumping jacks to set amazing records. In 2010, a huge event happened for the "Let's Move!" campaign. Over 300,000 people did jumping jacks in just 24 hours.

This event took place in 1,050 different locations.

Jumping jacks are a great way to see what your body can do. You can try to see how many you can do in one minute. A man named Binod Thapa set a record in Kathmandu, Nepal. On July 28, 2023, he performed 136 jumping jacks in one minute. You can even try different versions like split jacks. These use a staggered stance with one foot in front. It is a wonderful way to learn about movement and skill.

A jumping jack is a popular physical jumping exercise. It is often called a star jump. In the United States military, the move is known as a side-straddle hop. This exercise is a form of aerobic activity. It helps people stay active by using large movements of the limbs. People value it because it is a simple way to move the body. It can be done in many different settings, from schools to military training.

The movement follows a specific sequence of actions. To begin, a person stands with their feet together and arms at their sides. The person then jumps to a position where the legs are spread wide. At the same time, the arms swing overhead. Sometimes, the hands meet in a clap at the top. After this, the person jumps again to return to the starting position. This brings the feet back together and the arms back to the sides.

There are many variations that change the intensity of the exercise. Low impact versions involve stepping the legs to the side without jumping. In an intermediate version, the legs hop out to shoulder width while the arms rise. Power jacks are more intense because the person lands in a wide squat position. Squat jacks require the person to stay in a half squat while jumping. Star jumps are even more explosive. In a star jump, the legs swing out laterally in the air. The person then pulls the legs back to land in a tucked, narrow squat.

Other versions exist to protect the body or change the movement pattern. Half jacks are similar to regular jumping jacks. However, the arms only go halfway above the head. This variation was created to prevent rotator cuff injuries. These injuries can be linked to the repetitive motions of the standard move. Split jacks use a staggered stance. In this version, the right foot is in front of the left. The person swings an arm opposite to the jumping foot. They switch legs throughout the process to complete the exercise.

The history of the jumping jack is quite colorful. Some accounts suggest it dates back to 1885 at West Point Military Academy. A man named John J. "Black Jack" Pershing is said to have used it. He reportedly used the move as a method of hazing underclassmen, known as plebes. He would order them to count off into odd and even groups. He would then mimic pulling an imaginary string to make them move. The students moved their limbs like marionettes while upperclassmen watched.

While some think the name comes from the general, that is not true. The name actually comes from a jumping jack children's toy. This toy makes similar motions when the strings are tugged. Even though he did not invent the move, Jack LaLanne helped it become famous. He was a fitness expert who used the exercise in his television programs. His work helped popularize the jumping jack across the United States. This helped turn a military drill into a common fitness tool.

People have used jumping jacks to set impressive records and participate in large events. In 2010, National Geographic Kids organized a massive event. This was part of Michelle Obama's "Let's Move!" campaign. The event took place in 1,050 different locations. During a 24-hour period, 300,365 people were measured doing jumping jacks for one minute. This showed how the exercise can bring huge groups of people together. It also demonstrated the scale of global fitness campaigns.

Individual skill can also be measured through speed and repetition. A significant record was set recently in Kathmandu, Nepal. On July 28, 2023, a man named Binod Thapa performed 136 jumping jacks in one minute. This shows the high level of coordination and stamina required. Science also looks at how different squat depths affect the jump. Studies show that jumping from a shallower squat helps achieve greater height. However, deeper squats are better for improving vertical jump height. These details show how much science is involved in simple movement.
