How Many Calories Does 100 Jumping Jacks Burn Off?

Adults will burn roughly between one and two calories per jumping jack when performing them at a moderate intensity. Those performing jumping jacks should be aware that they are considered a high-impact exercise, as the constant jumping wears on the joints of the hips, knees and ankles. Before using jumping jacks as a substitute for other cardiovascular exercises, a physician should be consulted.

For safety, jumping jacks should be done on a soft surface and with appropriate footwear.
