"Seal Jacks" is a video demonstrating a variation of jumping jacks that incorporates arm movements similar to a seal's flipper motions. In seal jacks, instead of raising the arms overhead like in traditional jumping jacks, the arms are extended straight out to the sides at shoulder height while jumping the feet apart and together. This exercise targets the shoulders, chest, and cardiovascular system, while also engaging the legs and core for stability. The video typically emphasizes proper form, pace, variations, and the benefits of seal jacks as a dynamic warm-up or cardio exercise to improve overall fitness and endurance.
