Seated V-Up

Exercise Overview

The Seated V-Up is a challenging bodyweight core exercise that develops abdominal strength, balance and coordination by combining upper and lower body movement into a single repetition. Unlike traditional crunches that primarily target the upper abdominal muscles, the Seated V-Up requires both the torso and legs to move simultaneously, increasing the demand on the entire core.

During the exercise, the abdominal muscles work to flex the spine while stabilising the pelvis, as the hip flexors lift the legs towards the torso. Maintaining balance throughout the movement also recruits the deep stabilising muscles of the core, making the Seated V-Up an excellent exercise for improving overall trunk control.

The Seated V-Up requires no equipment and can be performed almost anywhere, making it suitable for home workouts, circuit training, functional fitness and athletic conditioning programmes.

The Seated V-Up challenges both the superficial and deep abdominal muscles while requiring constant balance and postural control throughout the exercise.

How to Perform the Seated V-Up

1. Sit on an exercise mat with your knees bent and your feet flat on the floor.
2. Lean your upper body backwards slightly while maintaining a straight back.
3. Extend your arms forwards in front of your body.
4. Lift your feet from the floor and balance on your sitting bones.
5. Extend your legs while simultaneously lowering your torso slightly.
6. Tighten your abdominal muscles throughout the movement.
7. Bring your knees back towards your chest while raising your torso.
8. Reach your hands towards your shins or feet at the top of the movement.
9. Pause briefly while squeezing your abdominal muscles.
10. Repeat using slow, controlled repetitions.

Avoid allowing your feet to touch the floor between repetitions if possible, maintaining continuous tension throughout the set.

Breathing Technique

• Inhale while extending your legs.
• Exhale as you bring your knees towards your chest.
• Maintain controlled breathing throughout the movement.
• Avoid holding your breath during longer sets.

Benefits

Strengthens the Entire Core

The Seated V-Up recruits the rectus abdominis, obliques and deep stabilising muscles throughout every repetition.

Improves Balance and Coordination

Balancing on the hips while moving both the upper and lower body develops body awareness and neuromuscular control.

Builds Muscular Endurance

Continuous tension throughout the movement improves abdominal endurance and control.

No Equipment Required

The exercise can be performed almost anywhere using only your bodyweight.

Supports Athletic Performance

A stronger, more stable core improves movement efficiency during running, jumping, lifting and rotational sports.

Common Mistakes

Rounding the Lower Back Excessively

Maintain a controlled, neutral spine as much as possible rather than collapsing through the lower back.

Using Momentum

Swinging the arms or legs reduces muscular activation and makes the exercise less effective.

Allowing the Feet to Rest

Keeping the feet elevated maintains continuous tension on the abdominal muscles.

Moving Too Quickly

Fast repetitions often sacrifice technique and reduce time under tension.

Looking Downwards

Keep your head aligned with your spine throughout the exercise.

Expert Tips

• Tighten your abdominal muscles before every repetition.
• Move slowly and deliberately.
• Keep your chest lifted throughout the exercise.
• Extend your legs only as far as you can while maintaining good control.
• Focus on controlled breathing.
• Stop the set when you can no longer maintain proper posture.

Variations

• Bent Knee Seated V-Up
• Straight Leg V-Up
• Weighted Seated V-Up
• Medicine Ball V-Up
• Alternating V-Up
• V-Up Hold
• Twisting Seated V-Up

Alternative Exercises

• V-Up
• Reverse Crunch
• Bicycle Crunches
• Flutter Kicks

Programming

Core Strength

• 3–4 sets
• 10–15 repetitions
• 45–60 seconds rest

Muscular Endurance

• 2–4 sets
• 15–20 repetitions
• 30–45 seconds rest

Circuit Training

• 30–45 seconds per round
• Minimal rest between exercises

Suitable For

The Seated V-Up is suitable for:

• Intermediate exercisers
• Advanced athletes
• Home workouts
• Functional fitness
• Core strengthening programmes
• Circuit training
• Sports conditioning
• Bodyweight training

Beginners can perform a bent-knee variation until sufficient core strength has been developed.

Avoid If

You may need to modify or avoid this exercise if you have:

• Acute lower back pain
• Hip flexor injuries
• Recent abdominal surgery
• Severe spinal conditions

If discomfort develops during the movement, reduce the range of motion or substitute an easier abdominal exercise.

Frequently Asked Questions

What muscles does the Seated V-Up work?

The Seated V-Up primarily targets the rectus abdominis while also engaging the hip flexors, obliques, transverse abdominis and several stabilising muscles throughout the core.

Is the Seated V-Up suitable for beginners?

The full version is generally better suited to intermediate exercisers. Beginners should start with bent-knee variations before progressing to full repetitions.

What’s the difference between a Seated V-Up and a regular V-Up?

A Seated V-Up begins from a seated balancing position and typically uses a smaller range of motion, whereas a traditional V-Up starts lying flat on the floor and involves lifting both the upper body and legs simultaneously.

How many repetitions should I perform?

Most people perform between 10 and 15 controlled repetitions per set for strength, or higher repetitions when focusing on muscular endurance.

Why do I feel the exercise in my hip flexors?

The hip flexors naturally assist with lifting the legs. Improving abdominal strength and maintaining proper technique can help increase core activation while reducing excessive reliance on the hip flexors.

Exercise Summary

The Seated V-Up is an excellent bodyweight exercise for strengthening the entire core while improving balance, coordination and muscular endurance. By combining upper-body and lower-body movement into one controlled repetition, it effectively challenges the abdominal muscles, hip flexors and deep stabilisers of the torso. When performed with proper technique and controlled movement, the Seated V-Up provides an effective addition to any core strengthening or athletic conditioning programme.
