V-Up

A dynamic core exercise where arms and legs meet in the middle, forming a V shape.

Short answer

V-Up: an intermediate bodyweight exercise for the abs and hip flexors. It needs no equipment. A typical target: 3 sets of 12-20 reps. If it is still too hard, start with the easier variation, “Tuck-Up”. Once it feels easy, “V-Up Hold” is the next step.

Target Muscles

What muscles does the v-up work?

The rectus abdominis contracts through its full range as the torso and legs meet, which makes this a more complete abdominal contraction than a crunch. The hip flexors raise the legs and contribute substantially. The quads keep the knees locked, and the shoulders work to keep the arms extended. Because both ends of the body move at once, the abs work against a longer lever than in any single-ended movement.

How to train it

Three sets of 12 to 20 reps, two or three times a week. Progress from tuck-ups with bent knees, to single-leg V-ups, to the full version. Slowing the lowering phase adds far more than extra reps. Because the movement flexes the spine repeatedly, alternate it with anti-extension work such as planks and rollouts rather than doing only this.

If you are stuck

Bending the knees shortens the lever and is a fine regression as long as it is deliberate. Using momentum - bouncing off the floor between reps - is the fault that hollows out the exercise; pause briefly at the bottom. Not reaching a full V means the abs never reach their shortened position, which is where the contraction is strongest; reach your hands towards your feet at the top rather than stopping halfway.

V-Up questions

What is the difference between V-ups and sit-ups?

V-ups work both upper and lower abs by lifting legs and torso simultaneously, meeting in the middle. Sit-ups only lift the torso. V-ups are more challenging and provide more complete ab activation.

How do I do V-ups without using momentum?

Control the descent - lower slowly back to start rather than dropping. Pause briefly at the bottom before the next rep. If you cannot control it, try tuck V-ups (bent knees) first.

Why do V-ups hurt my lower back?

You may be relying on hip flexors and arching your back. Focus on pressing your lower back into the floor at the start and using your abs to curl up. Try the easier "hollow body crunch" variation first.
