Alternating Leg V-Up
Alternating Leg V-Up Exercise Description
The Alternating Leg V-up is a bodyweight trunk-flexion exercise that trains the anterior core with a unilateral demand. You’ll lift one leg at a time while curling the torso, creating a controlled “V” shape as the opposite hand reaches toward the raised leg. Primary muscles include the rectus abdominis, with important contributions from the external and internal obliques for trunk flexion and rotational control. The hip flexors (iliopsoas and rectus femoris) assist by raising the leg, while the transverse abdominis stabilizes the lumbopelvic region. Alternating sides introduces an anti-rotation challenge that encourages even, symmetrical control through the waist. The focus is on precise sequencing—bracing, curling the upper torso, and lifting the leg—while maintaining a neutral neck and stable lower back.

How To Do The Alternating Leg V-Up Exercise
‘- Lie supine on a mat, legs extended, heels lightly on the floor; arms overhead in line with ears, palms facing each other.
– Set your brace: ribs down, gentle posterior pelvic tilt to keep the lower back lightly in contact with the mat.
– Inhale to prepare; chin slightly tucked, shoulders down and away from ears.
– Exhale as you curl head, shoulders, and upper back off the floor while raising the right leg, knee mostly straight.
– Reach the left hand toward the right shin/ankle; keep the right arm long by the ear.
– Pause briefly when your torso and raised leg form a “V,” keeping the opposite leg extended on the floor.
– Inhale to lower the torso and leg with control, returning through the spine without collapsing.
– Switch sides on the next repetition: raise the left leg and reach with the right hand.
– Keep movement smooth; avoid swinging the leg, yanking on the neck, or letting the low back arch off the mat.
– Use a comfortable range of motion; only lift as high as you can maintain lumbopelvic control.
Alternating Leg V-Up Tips
‘- Lie supine with legs extended, heels lightly on the floor, and arms overhead in line with your ears, palms facing each other.
– Set your brace before moving: bring the ribs down and use a gentle posterior pelvic tilt so the lower back stays lightly in contact with the mat.
– Keep the chin slightly tucked and shoulders down and away from the ears to maintain a neutral neck as you move.
– Exhale as you curl the head, shoulders, and upper back off the floor while raising one leg, keeping that knee mostly straight.
– Reach the opposite hand toward the raised leg’s shin or ankle while keeping the same-side arm long by the ear to form a controlled “V” shape.
– Pause briefly in the “V” position with the opposite leg extended on the floor before returning.
– Inhale to lower the torso and leg with control, letting the spine return to the mat without collapsing.
– Switch sides on each repetition, alternating the raised leg and reaching hand to promote even, symmetrical control through the waist.
– Keep the movement smooth; avoid swinging the leg, yanking on the neck, or letting the low back arch off the mat.
– Use a comfortable range of motion, lifting only as high as you can while maintaining lumbopelvic control and light contact of the lower back with the mat.
Alternating Leg V-Up Beginner Introduction
The Alternating Leg V-up is a bodyweight core movement that blends a crunch-like action with a single-leg raise. It targets the abs and side abs, with help from the hip flexors and the front of the thighs as the leg lifts. During each repetition, the upper body folds toward one leg while the opposite hand reaches toward it, creating a V-shaped position between the chest and the lifted leg, while the other leg remains extended on the floor.
Because the reach and leg lift switch from side to side, the exercise challenges the waist to stay steady against unwanted twisting. This places a strong demand on the deep abs to support the lower back and pelvis so the motion feels controlled rather than swinging. The movement highlights smooth coordination: tension through the midsection, a curling action through the upper body, and a precise single-leg lift, all performed with calm neck positioning and a grounded, supported lower back.
