General Information
Exercise Ball V-Up is a compound exercise that primarily targets the rectus abdominis across its full length and also engages the hip flexors and obliques. It is an intermediate-level movement that combines an upper-body crunch with a lower-body leg raise into one coordinated action, using the exercise ball as a transfer object between the hands and feet.
The exercise begins lying flat on the floor with the ball held overhead in both hands. The arms and legs simultaneously rise to meet at the top, where the ball is passed from the hands to the feet (or vice versa). The body then lowers back to a fully extended position before repeating the transfer in the opposite direction. This full-range motion demands strong coordination and continuous tension through the entire abdominal wall.
Because both the upper and lower portions of the rectus abdominis must contract forcefully to bring the limbs together, the Exercise Ball V-Up is considerably more demanding than isolated movements like the Exercise Ball Crunch or the Exercise Ball Pull-In. The ball itself adds a proprioceptive challenge, as the trainee must grip and release it cleanly at the top of each rep.
This exercise works well as a core finisher or as the centerpiece of an abdominal circuit. It pairs effectively with anti-extension exercises like the Exercise Ball Plank and anti-rotation work like the Exercise Ball Russian Twist for a well-rounded core session.
The key to getting the most from this exercise is controlling the lowering phase. Allowing the arms and legs to drop quickly under gravity wastes the eccentric portion, which is where a significant amount of abdominal recruitment occurs. Lower slowly on every rep, keeping the lower back pressed into the floor.

Instructions
- Lie flat on your back on the floor with your legs extended and the exercise ball held overhead in both hands, arms straight.
- Brace your core and press your lower back firmly into the floor.
- Simultaneously raise your arms and legs toward each other, keeping both as straight as possible.
- At the top of the movement, transfer the ball from your hands to between your feet or ankles, squeezing it firmly.
- Lower both your arms and legs back to the fully extended starting position in a controlled manner without letting them touch the floor.
- Raise your arms and legs again to meet at the top and transfer the ball back from your feet to your hands.
- Lower back down with control to complete one full repetition.
- Continue alternating the ball transfer for the prescribed number of reps.
Common Mistakes
Injuries
Exercise Ball V-Up is a medium risk exercise when performed with proper technique. The primary concern is the lower back, which can be strained if the lumbar spine arches excessively during the lowering phase when both arms and legs are extended.
The most vulnerable moment occurs at the bottom of each rep. As the limbs extend away from the center of mass, the hip flexors pull on the lumbar spine, creating an anterior pelvic tilt. If the abdominals are not strong enough to counteract this force, the lower back lifts off the floor and absorbs compressive load. To prevent this, only lower the limbs as far as you can while keeping the lower back flat against the ground.
Individuals with existing hip flexor tightness may also find that the psoas dominates the leg-lifting portion, causing discomfort in the front of the hip. If this happens, slightly bending the knees reduces the lever arm and shifts emphasis back to the abdominals.
Stop the exercise if you feel pinching in the lower back, cramping in the hip flexors that does not resolve between reps, or loss of the ability to control the ball during transfers.
Frequently Asked Questions
- Q: What size exercise ball should I use?
A standard 55 to 65 cm ball works for most people. The ball needs to be large enough to grip comfortably between the ankles but not so large that it is awkward to pass at the top of the movement.
- Q: How is this different from a regular V-up?
The ball adds a transfer element that forces you to maintain tension at the top of each rep and keeps the limbs engaged during the lowering phase. It also provides tactile feedback that helps with coordination.
- Q: Can beginners do this exercise?
Beginners may struggle with the coordination and core strength required. A good progression path is to start with the Exercise Ball Pull-In or Exercise Ball Crunch, then advance to this movement once basic ball exercises feel manageable.
- Q: How many reps per set is typical?
Aim for 8 to 12 reps per set. Each full transfer cycle (hands to feet and back) counts as one rep. Quality matters more than quantity here, so reduce the count if form starts to break down.
