Balancing on your tailbone with legs and torso raised into a V, you hold the position rather than rep it, so the abs and hip flexors work isometrically against both levers at once. Time is the progression here - start with ten-second holds, and bend the knees slightly if the low back starts to round.
How to do the Floor V-Sit
- Sit on the floor with your legs extended in front of you.
- Lean back slightly and lift your legs off the ground, keeping them straight.
- Simultaneously, lift your upper body off the ground and reach your arms towards your legs.
- Hold this position for a few seconds, then slowly lower your upper body and legs back down to the starting position.
- Repeat for the desired number of repetitions.
Tip: Breathe out as you crunch and let the last bit of air leave the lungs at the top of each rep.
Muscles worked
Primary
Abs · Core
The rectus abdominis shortens to bend the spine forward, and each rep should end with the upper abs fully contracted and the ribs pulled down.
Secondary
- Hip Flexors — The hip flexors take over if your feet are anchored and you come up too high; keep the range short to leave them out.
Common mistakes
- Pulling on the neck — hands behind the head should support, not yank; keep the elbows wide and the chin about a fist away from the chest.
- Sitting all the way up — a crunch is a curl of the ribs toward the pelvis, not a sit-up; the lower back should stay on the floor the whole time.
- Cranking out fast reps — momentum does the work if you bounce; lift to a squeeze, hold for a count and lower slowly.
- Never adding load — once bodyweight reps get easy, hold a plate on the chest or use a cable rather than doing sets of 50.
Where it fits in a workout
Crunches close out a session after the heavy work, or they can fill the rest periods between sets of a lift that does not need much bracing. Pair a cable crunch with a cable side bend on the same stack.
How many sets, how heavy and how hard: see what the ACSM position stands support.

When to talk to someone
- Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
- Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
