Trunk Flexion


Purpose: This exercise develops strength in the abdominal muscles (Figure 6-52).

Starting Position: Seated position with the feet firmly on the ground. Select the appropriate weight and ensure the pin is secure in the weight stack. The seat is adjusted so the chest pad is located on the upper chest, below the collarbone. The elbows are shoulder-width apart and bent at 90 degrees, with hands in a closed-grip. The hips and low back are firmly against the seat back with the eyes looking straight ahead.

Cadence: SLOW


  1. Bend forward, flexing the trunk, and bringing the chest pad to the thighs.
  2. Return to the starting position.
