Table Of Contents

When it comes to getting a great workout, few exercises can compare to the v-up. Also known as the "jackknife," this move works virtually every muscle in your body, making it an ideal choice for those looking to get fit.

The V-up is a challenging yet rewarding exercise that works the entire core. Though it may look simple, don't be fooled - this move requires serious strength and coordination. But trust us, it's worth the effort. Not only will you develop killer abs, but you'll also build explosive power and improve your overall athleticism.

If you're looking for a challenging core workout, you can't go wrong with v ups. This exercise targets the abs, obliques, and lower back, making it an ideal move for those looking to strengthen their core. And because it's a compound exercise, you'll work your legs and arms.

This article will guide you through the right technique to perform V-Ups, their adaptations, the muscle it targets, their benefits, and the mistakes to avoid when you try these moves. By the end of this article, you will be compelled to add V-Ups to your workout routine.

What is a V-Up and How to do It?

The V-up is a classic exercise that adds the needed challenge to your workout routine if you want to tone your midsection. The best part about this exercise is that it can be easily performed at home as it requires nothing more than your body weight and an optional yoga mat. Here's how to do it:

  • Lie on your back with your legs straight and your arms at your sides.
  • Slowly raise your legs and torso off the ground, keeping your legs together and reaching your hands toward your feet.
  • Reverse the motion to return to the starting position.
  • That's one rep. Start with sets of 10 reps and work up to sets of 20 or more.

To make the V-up more challenging, you can add weight to the exercise or try doing it with one leg raised off the ground. You can also try adding a twist by reaching one hand to the opposite foot as you raise your torso. Give it a try and see how it feels!

What Muscles Do V-Ups Work?

V-Ups are a great way to work your core muscles. The main muscle group that V-Ups targets is the rectus abdominis, which is the muscle that runs along the front of your stomach. This muscle is responsible for flexing your spine, and it's what gives you that six-pack look.

V-Ups also work your obliques, the muscles that run along the sides of your stomach. Obliques are responsible for the rotation and side bending and help stabilize your spine.

In addition to these two major muscle groups, V-Ups also work your erector spinae, a group of muscles that runs along your spine. These muscles extend and rotate your spine, which is essential for good posture.

Benefits of V-Ups

V-Ups come with primary benefits for your body. Here are some of them:

Stronger Core

If you're looking for a workout that will leave you feeling sore in all the right places, look no further than the v-up. This simple exercise is amazingly effective at working the entire core, from the abs to the obliques to the lower back.

And it's not just your midsection that will benefit from this move — strong core muscles are essential for good posture and proper alignment and can even help improve your balance. So if you're looking to build a strong foundation for your fitness journey, add some v ups to your routine.


Anyone who's ever tried to do a v-up knows that they are not easy. They are pretty darn hard. But that's precisely why they are such a great exercise. Not only do they work your abs, but they also help improve your balance.

The key is to keep your body as straight as possible as you lift your legs and torso off the ground. This forces your core muscles to engage, which in turn helps improve your balance.

Protects Lower Back

V-ups are excellent exercises to keep your lower back healthy and prevent injury. By engaging your core muscles, V-ups help stabilize your spine and pelvis. This, in turn, takes the pressure off your lower back and can help prevent pain and injury.

V-Ups Adaptations

V-Ups are one of the most popular core exercises, and for a good reason. They're simple to do, work various muscles, and can be done anywhere. However, as with any exercise, mixing things up from time to time is important to avoid plateauing. Here are a few V-Up variations to keep your workout interesting.

V-Ups With Medicine Ball

Try adding a medicine ball for a challenging twist on the traditional V-Up. Here’s how to do it:

  • Holding the ball in both hands, extend your legs and arm out long.
  • Keep your low back pressed into the ground at all times.
  • Explode forward and bring the ball towards your feet.
  • Lower back down and extend your limbs to the starting position.
  • For an added challenge, try passing the ball back and forth between your hands and feet without letting it touch the ground.

If you're looking for a way to increase the intensity of your V-Ups without adding weight, try doing them on an unstable surface like a BOSU ball. The instability will force your muscles to work harder to maintain balance, resulting in a more effective workout.

V Ups With Dumbbell

V-Ups are a great way to work your core, but they can be tough without the right equipment. Dumbbells are the perfect tool for the job, and with a little practice, you'll be nailing them in no time. Here's how to do it:

  • Start lying on your back and hold the dumbbell firmly with both hands.
  • Raise your legs and arms to point straight up toward the ceiling. Then, keeping your core engaged, lift your torso and upper legs off the ground and bring them up to meet in the middle.
  • Lower back down and repeat.
  • Remember to keep that lower back firmly on the floor throughout the movement.

Seated V Ups

If you struggle to reach a full range of motion, this V-up variation will act as a golden key. While most of the moves of the exercise would remain to be the same, here’s what is different:

  • Start from a seated position instead of lying down flat on your back.
  • From there, support yourself with your hands on the ground and drive your knees into your mid-section.
  • Extend out to the starting position.

The Side V-Up

If you are a beginner wanting to add a little bit of zeal to your workout, this variation can help:

  • Start a side lying position, with your forearm supported on the ground.
  • Laterally crunch your abs, bringing your elbow towards your knees.
  • Return to the starting position and repeat on the other side.

This will still give you a good ab workout without taking a toll on the lower back. You can gradually work your way down to the traditional starting position as you get stronger. Mixing things up and trying new variations allows you to keep your workouts interesting and effective.

V-Up Mistakes to Avoid

With any move, a few mistakes can quickly turn the V-Up from an effective workout into an injury risk. Here are a few V-Up mistakes to avoid:

Don't Let Your Hips Sag

This is a common mistake that people make when doing V-Ups. Letting your hips sag puts unnecessary stress on your lower back, which can lead to pain or even injury. Instead, keep your core engaged throughout the entire move.

Don't Rely on Momentum

Using momentum to help you get through the reps is tempting, but this is a mistake. Not only will it make the exercise less effective, but it also increases your risk of injury. Remember: slow and controlled is the way to go.

Don't Arch Your Back

Another common mistake people make when doing V-Ups is arching their back. This puts unnecessary strain on the spine and can lead to pain or injury. Instead, keep your back flat throughout the entire movement.

Not Engaging Your Abs

This is the most common mistake people make when doing v-ups. Remember, your abs will help lift your body off the ground, so you must ensure you activate them. To do this, think about exhaling as you lift your body and keeping your abs pulled in tight throughout the entire movement.

Swinging Your Arms

Finally, many people make the mistake of swinging their arms around when they do v-ups. This actually makes it harder to balance and can throw off your whole form. Instead, keep your arms close to your sides and focus on using your core to lift your body.

By avoiding these common mistakes, you'll be able to get the most out of your V-Ups and stay safe in the process. So next time you're ready to work out, remember to keep these tips in mind!


1. What are CrossFit V-Ups ?

CrossFit V-Ups works your core, arms, and legs and can be modified to fix your fitness level. Here's how it's done:

  • Start by lying on your back with your legs straight and your arms at your sides.
  • From there, engage your core and lift your legs and upper body off the ground.
  • As you do so, reach your hands towards your feet.
  • Return to the starting position and repeat.

Not only is this exercise great for toning your body, but it's also a great way to get your heart rate up. So if you're looking for a workout that will make you sweat, CrossFit v-ups is a perfect choice.

2. How to do V-Ups?

Here's how to do V-Ups,

  • Lie flat on the floor with your legs extended and your arms at your sides.
  • Keeping your legs straight, raise them up until they're pointing toward the ceiling.
  • At the same time, lift your upper body off the floor, reaching your hands toward your feet.
  • Try to touch your toes or as close to them as you can.
  • Slowly lower yourself back to the starting position and repeat.

Remember: keep that core engaged throughout the entire movement, and don't let your lower back arch off the floor. Try bending your knees slightly to make the exercise easier if you struggle. And always warm up before attempting any new exercise!

3. List some v-ups for beginners.

There are plenty of fun and challenging v-ups for beginners that will help you get in shape without feeling like you're stuck in a rut. Here are just a few examples:

The Basic V-Up:

  • Start lying on your back with your legs extended and your arms at your sides.
  • Slowly lift your torso and legs off the ground, keeping them together as you reach up toward the ceiling.
  • Reverse the motion to return to the starting position.

The Alternating V-Up:

This is a variation of the basic v-up in which you alternate lifting your right and left sides independently of each other. This move is great for toning your obliques (the muscles on the sides of your waist).

The Stability Ball V-Up:

  • Start by lying on top of a stability ball with your feet flat on the ground and your hands behind your head.
  • Keep your lower back pressed into the ball.
  • Lift your torso and legs off the ground and reach forward with your hands until they meet in front of your feet.
  • Reverse the motion to return to the starting position.

This move is more challenging than the others because you have to maintain balance on top of the ball, but it's also great for strengthening your core muscles.

4. What are Burpees?

Burpees are one of the most intense exercises you can do. They are a full-body workout that gets your heart rate up and burns calories. They are also a great way to tone your muscles.

Here is how to do it:

  • Start in a standing position, then lower down into a squat.
  • From there, put your hands on the ground and kick your feet back, in a push-up position.
  • Do a push-up, then jump your feet back to the squat position.
  • From there, stand up and jump as high as you can. That is one rep.

Burpees are tough, but they are also very effective. If you want to get in shape or challenge yourself, try doing some burpees!

The Bottom Line

The v-ups build strength and stability in the back, arms, shoulders, length, and core. This exercise can be performed without equipment, using your body weight.

There are many adaptations of the v-ups that can be performed to target different muscle groups and try challenging workouts. Common mistakes to keep in mind before carrying out the workout, like sagging the hips or arching your back, are important to consider.
