To recap slightly, a cold air intake works by pulling in cooler more oxygen rich air while a short ram pulls in warmer air but at a faster rate.However, itâs very important to understand that because the intake is located near your engine, the air being pulled in is warmer than a CAI.
Wall sit exercise, side view. A wall sit is an exercise done to strengthen the quadriceps muscles. It is characterized by the two right angles formed by the body, one at the hips and one at the knees. The person wall sitting places their back against a wall with their feet shoulder width apart and a little ways out from the wall.
If you were to look at the image to the left these are ALL the muscles of the hip flexorsâ¦ if you notice that the abdominal wall is NOT one of them. These are the PRIME movers in decline sit-ups and most other sit up variations. So doing countless reps and decline angles only further continues to improve the functionality and muscular development of the hip flexors, not develop the abdominal wall.
