ARMY JUMPING JACK! A jumping jack, also known as a star jump and called a side-straddle hop in the US military, is a physical jumping exercise performed by jumping to a position with the legs spread wide and the hands going overhead, sometimes in a clap, and then returning to a position with the feet together and the arms at the sides. #summercampforkids #summercamp2022 #sousleystengthandhonor #americasmilitarysummercamp | Military Adventure Camp at Camp Sousley
