What you'll gain

• Adds real strength stimulus to the situp pattern.

• Builds trunk flexion strength under external load.

• Bridges bodyweight ab work into loaded core training.

Step-by-Step Instructions

1. 1

   Lie on your back with knees bent at 90 degrees and feet flat on the floor or anchored under a pad.

2. 2

   Hold a dumbbell against your chest with both hands, hugging it close to your sternum.

3. 3

   Brace your core and tuck your chin slightly toward your chest before starting the rep.

4. 4

   Sit all the way up by curling your torso forward until your elbows pass over your knees.

5. 5

   Pause briefly at the top, keeping the dumbbell tight against your chest the whole time.

6. 6

   Lower yourself back down slowly under control until your shoulder blades touch the floor.

Common Mistakes

• Yanking the head and neck forward to start the rep, which strains the neck instead of the abs.

• Dropping back down quickly and bouncing off the floor instead of controlling the lowering phase.

• Holding the dumbbell out in front of the chest, which loads the shoulders instead of the abs.

• Hooking the feet too aggressively under a pad, which lets the hip flexors do most of the work.

About This Exercise

The dumbbell situp adds external load to the bodyweight situp by holding a dumbbell against the chest. The added weight makes every rep harder for the abs and gives the trunk a real strength stimulus instead of just an endurance one — useful for users who can already do high-rep bodyweight situps. This clip slots into intermediate ab blocks in any fitness app and into hypertrophy programs that include a weighted core finisher. It also pairs well in a coaching platform's strength education modules — a clean way to show progression from bodyweight situps into loaded core work without jumping straight to cable crunches or weighted decline situps.
