Weighted Decline Twist Sit Up

Muscles worked

Setup

1. Secure your feet firmly under the padded rollers of a decline bench set to a 30-45 degree angle.
2. Hold a dumbbell with both hands tucked tightly against your upper chest, just below your chin.
3. Sit back until your torso is roughly parallel to the floor to create initial tension in the abdominals.

How to do it

1. Exhale and curl your torso upward, focusing on rounding your spine slightly to engage the abs rather than pulling from the hip flexors.
2. As you reach the top third of the movement, rotate your torso to one side, aiming to point your elbow toward the opposite knee.
3. Inhale as you slowly lower your torso back to the starting position with a controlled 2-second eccentric phase.
4. Perform the next repetition by twisting to the opposite side, alternating sides for the duration of the set.

Form checklist

• Keep the dumbbell glued to your chest to prevent using arm momentum.
• Ensure the rotation occurs at the waist and ribcage, not just moving the shoulders.
• Maintain a slight 'C' curve in the spine to keep the tension on the abdominal wall.
• Avoid letting your shoulder blades touch the bench at the bottom to maintain constant tension.

Pro tips

• Focus on 'crunching' your ribcage toward your pelvis before you begin the twist to fully pre-shorten the rectus abdominis.
• Pause for a half-second at the peak of the twist to maximize the peak contraction of the internal and external obliques.

Make it harder

• Increase the decline angle of the bench to work against a steeper gravitational pull.
• Hold the dumbbell with arms slightly extended away from the chest to increase the lever arm and rotational difficulty.
