Abstract: An abdominal muscle exercise machine of a push-pull type that includes an elbow sliding support plate with handle bars; a knee sliding support plate with swiveling knee cups; elastic resistance bands attached between the elbow and knee support plates and the end stabilizer bars; parallel sets of shafts at the front and rear end of the machine connected to the sliding support plates; a center rod with support legs to raise it off the ground; quick release clamps attached to the parallel shafts; and end support rods with end caps at the front and rear end of the machine. The machine has a dual incline angle for both the elbows and knees to pull and push against during exercise and may be adjusted in range of motion using quick release clamps. The machine may also be easily folded closed for storing in a compact space.
