An inflatable cushion bag for striking includes an outer wall and an inner wall that is positioned inside and longitudinally with the outer wall looped around the inner wall. A first radial wall is joined to each of and connects between the outer wall and the inner wall at a first end and is sealed so that free airflow is blocked at the first end. A second radial wall is joined to each of and connects between the outer wall and the inner wall at a second end and is sealed so that free airflow is blocked at the second end. At least one intermediate radial wall is placed longitudinally between the first radial wall and the second radial wall and transversely between the outer wall and the inner wall. The intermediate radial wall may have a small opening such as a hole with a diameter less than ½ inches or an equivalent so that the opening allows a slow airflow through the intermediate radial wall for inflating or deflating the bag and, when inflated, restricts airflow through the opening to give a shock absorber effect to make the outer wall an added cushion when punched or kicked.
