Forward & Reverse Bear Crawl

Start on all fours and lift your knees to a 90-degree angle, hovering an inch off the ground. Keep your back flat, your legs hip-width apart and your arms shoulder-width apart. Move one hand and the opposite foot forward an equal distance while staying low to the ground. Continue forward until the prescribed distance is covered. Repeat the same movement but in the opposite direction until back at the starting postion.
