Dumbbell V-Up
The Dumbbell V-Up is a core exercise that adds external weight to the classic V-up to increase control and coordination.

Muscles Worked: Dumbbell V-Up
The Dumbbell V-Up mainly trains your abs because they curl your torso up and help hold the top position as your body folds into a V. Your hip flexors assist by lifting your legs and keeping them moving toward the dumbbell. Holding the weight in your hands also makes your midsection brace harder so you do not lose position. You should feel a strong squeeze through the front of your core, which fits research showing high abdominal activity in demanding trunk-flexion exercises (Schoffstall et al., 2010).
Technique and form
How to perform the Dumbbell V-Up
- Start by lying flat on your back on a mat with your arms extended overhead, holding a dumbbell with both hands.
- Keep your legs straight and positioned on the floor while your core remains engaged to stabilize your lower back.
- Inhale deeply and brace your core as you simultaneously raise your straight legs and arms toward the ceiling.
- As you lift, keep your shoulders relaxed and away from your ears while aiming to touch the dumbbell to your feet at the top of the movement.
- Maintain control throughout the motion, ensuring your lower back stays pressed into the mat to protect your spine.
- Exhale as you reach the peak position, where your body forms a V-shape with only your glutes touching the floor.
- Lower your arms and legs back to the starting position in a slow, controlled manner while inhaling.
- Keep tension in your abdominals throughout the entire movement, never fully relaxing at the bottom position before beginning the next repetition.
Important information
- If you feel strain in your lower back, bend your knees slightly or reduce the range of motion until your core strength improves.
- Focus on moving your limbs through the full range of motion rather than simply swinging the dumbbell toward your feet.
- Choose a lightweight dumbbell (2-10 lbs) when first learning this exercise to maintain proper form.
- Keep your neck neutral throughout the movement by focusing your gaze toward the ceiling rather than lifting your head to watch your feet.
Is the Dumbbell V-Up good for muscle growth?
Yes. The Dumbbell V-Up can help build your abs because it combines a hard crunch with a leg raise, which makes the front of your core work through a long range while resisting the pull of the weight. Research on abdominal exercise muscle activity shows that demanding trunk-flexion movements can produce high ab activation, which supports their use for muscle-building when you also add reps or load over time (Schoffstall et al., 2010).
- Loaded top squeeze — The dumbbell gives you a reason to finish every rep hard instead of just swinging your arms and legs together. That stronger squeeze at the top can make the exercise more useful than bodyweight-only versions when your regular V-ups get too easy.
- Longer working range — Your abs work from the floor all the way to the folded top position, while your hip flexors help bring the legs up. That long path gives your midsection more time under tension than short, half-rep crunches.
- Easy to progress — You can progress by adding a little dumbbell weight, slowing the lowering phase, or pausing at the top for 1-2 seconds. If this bothers your lower back or you cannot keep your legs straight, build up with the dumbbell-decline-sit-up first.
- Best for focused ab work — This is an isolation-style core move, so it fits well after bigger lifts when you still want direct ab training without a lot of whole-body fatigue. It also pairs well with simpler floor work if you want extra volume after exercises like the push-up-to-renegade-row, which train the core in a different way.
Programming for muscle growth
Do 2-4 sets of 8-15 reps with 45-75 seconds rest, 1-3 times per week. Use a load that lets you keep your lower back from popping off the floor too early and reach the top under control. If you can do 15 clean reps on every set, increase the dumbbell slightly or add a 1-second pause at the top before lowering the weight slowly.

FAQ - Dumbbell V-Up
The Dumbbell V-Up primarily targets your rectus abdominis (six-pack muscles) and hip flexors, while also engaging your transverse abdominis for stability. The added resistance from the dumbbell increases activation throughout your entire core region compared to standard V-Ups.
Lie flat on your back holding a dumbbell with both hands extended overhead. Simultaneously raise your straight legs and upper body off the floor while bringing the dumbbell toward your feet, creating a "V" shape. Lower back down with control, without letting your limbs touch the ground between reps.
Start with a light dumbbell (5-10 lbs) to master the movement pattern before progressing. The ideal weight allows you to maintain proper form for 8-12 reps while still feeling challenged in your core, not your arms or shoulders.
The most common errors include using momentum rather than core strength, rounding the lower back excessively, pulling with the neck instead of engaging abs, and selecting a dumbbell that's too heavy. Focus on controlled movement and maintaining a neutral spine throughout the exercise.
You can make Dumbbell V-Ups easier by bending your knees, performing just the upper body portion while holding the dumbbell, or doing alternating sides instead of the full movement. For beginners, master the basic V-Up without weight before adding resistance.
