The Dumbbell V-Up is an advanced core exercise that targets the entire abdominal wall and hip flexors by synchronizing a leg lift with an upper body crunch. Adding a dumbbell increases resistance, demanding greater stability and strength from the rectus abdominis and deep core muscles.

Setup
- Lie flat on your back on a mat with your legs extended straight and feet together.
- Hold a single dumbbell with both hands, extending your arms straight overhead.
- Engage your core to press your lower back firmly into the floor.
How to do it
- In one fluid motion, exhale and lift your legs and torso simultaneously to form a 'V' shape with your body.
- Reach the dumbbell toward your feet, keeping your arms and legs as straight as possible throughout the movement.
- Inhale as you slowly lower your torso and legs back to the starting position with a controlled 2-second tempo.
- Stop just before your heels and the dumbbell touch the floor to maintain constant tension.
Form checklist
- Keep your legs straight and squeezed together to engage the hip flexors and quads.
- Avoid arching your lower back as you lower your limbs back to the floor.
- Keep your neck neutral and avoid leading the movement with your chin.
- Ensure the upper and lower body rise and fall at the same rate.
Pro tips
- Focus on 'folding' at the hips rather than just lifting the limbs to ensure maximum abdominal contraction.
- Pause for a split second at the top of the 'V' to emphasize the peak contraction of the rectus abdominis.
Make it harder
- Perform the movement with a 'hollow hold' at the bottom, never letting your shoulder blades or heels touch the mat.
- Increase the lever length by holding the dumbbell further back behind your head during the eccentric phase.
