Take your standard sit-up to a new level. By placing the mat against the hip, tucked into the low back, we accomplish a few things. First, we fill the gap between the floor and our lumbar spine which reduces unwanted shearing pressure on the back as we generate force in the sit-up. The mat gives the athlete something to press against. But secondly, when we lay back and reach our hands up above our heads, we lengthen our torso and open the abdominals up creating eccentric force on the stomach. This leads to harder workouts, more intensity and pronounced results.
