What is the Camera Jumping Jack Counter?
Jumping jacks are fast and easy to lose count of. Face your camera, step back until your whole body is visible and start: a rep counts when your arms go overhead and your feet jump wide, then return to hands down and feet together.
It works at any angle and gives a spoken count, so you can focus on the cardio. Set a goal such as 50 or 100 and the coach calls it when you reach it.
