The verdict

Leg Pull-In has 4-step instructions, documented to a similar depth as most of the 93 abdominals exercises PlainExercise catalogues.

Ranked against the 93 abdominals exercises PlainExercise currently catalogues, not the full exercise-science literature.

Source Free Exercise DB · 2026-07-10

Leg Pull-In is documented from the Free Exercise DB (CC0) extract, last ingested July 2026. Classification, muscle roles and instruction text are source facts; the placement and cohort measures on this page are computed by PlainExercise and are not a rating of the movement.

What the Leg Pull-In Data Reveals · DOC · PULL/COMPOUND

Leg Pull-In stands out on force direction, the first filter on this record.

A mid-length step list is enough detail to compare form without the longest upstream essays.

Across 93 catalogued abdominals movements, the average instruction record is 645 characters and 4.7 steps; 68 of those (73.1%) clear the same ≥500-character rich bar used here. This page ranks #48 of 93 by instruction-character length (99.1% of the cohort average).

Among the 111 exercises that also use just bodyweight, average instruction length is 581 characters; 37 of those peers are longer than this record. Equipment-matched peers are the honest comparison when you are choosing a substitute implement for the same pattern.

Context matters: taxonomy (level, mechanic, force, musculature, equipment) does not account for individual biomechanics, joint history, or recovery. Common-mistake framing below is derived from classification fields, not case-specific coaching. Not medical or personal-training advice. Consult a physician or certified trainer before starting, especially with injuries, cardiovascular conditions, recent surgery, or pregnancy.

Leg Pull-In catalog footprint

Among 93 exercises whose primary muscle is abdominals, Leg Pull-In ranks #12 by catalogued variation count. The upstream file attaches 2 images to this slug. See the step-count ranking for abdominals for peer documentation depth.

Muscles worked

The Free Exercise DB classifies each muscle as primary or secondary. It does not measure activation, so we show involvement, not percentages.

Intensity context

For reference, here is where common activities sit on the MET intensity scale. Leg Pull-In does not have a measured MET in the source data, its intensity depends on the load and effort you use. Estimate calories for any activity with the calorie calculator.

MET Intensity Zones, Exercise Intensity Chart Horizontal bar chart showing how six common exercises map to four MET intensity zones: Light (1-3 MET), Moderate (3-6 MET), Vigorous (6-9 MET), and Very Vigorous (9+ MET). Walking at 3.5 MET falls in Moderate; Jump Rope at 12.3 MET reaches Very Vigorous. Light Moderate Vigorous Very Vigorous 0 3 6 9 12 15 MET (Metabolic Equivalent of Task) Walking 3.5 Cycling 6.8 Jogging 7 Swimming 9.8 Jump Rope 12.3 Light (0-3 MET) Moderate (3-6 MET) Vigorous (6-9 MET) Very Vigorous (9-+ MET)

MET values from the Compendium of Physical Activities (Ainsworth et al., 2011). A general reference scale, not a rating of this specific movement.

How to do it

  1. Lie on an exercise mat with your legs extended and your hands either palms facing down next to you or under your glutes. Tip: My preference is with the hands next to me. This will be your starting position.
  2. Bend your knees and pull your upper thighs into your midsection as you breathe out. Continue the motion until your knees are around chest level. Contract your abs as you execute this movement and hold for a second at the top. Tip: As you perform the motion, the lower legs (calves) should always remain parallel to the floor.
  3. Return to the starting position as you inhale.
  4. Repeat for the recommended amount of repetitions.

Common mistakes

  • Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Leg Pull-In teaches the nervous system the movement far faster than speed does.
  • Cutting the range of motion short - moving the abdominals through its full safe range on Leg Pull-In is what most reliably separates effective reps from wasted ones.
  • Treating a compound lift like an isolation movement - Leg Pull-In recruits multiple joints; bracing the core and engaging stabilizers matters as much as the prime movers.
  • Shrugging the shoulders up toward the ears on pull movements, keep shoulder blades down and back to load the correct muscles.
  • Breathing out of sync with the lift on Leg Pull-In - brace and inhale during the lowering phase, exhale on the exertion, especially important with just bodyweight where control matters most.

Who this is for

  • People new to resistance training who want to build a foundation in the movement pattern
  • People who want to train the Abdominals
  • People training at home without equipment

Who this is NOT for

  • People hunting equipment swaps, this record has none to offer; browse the peer abdominals exercises for alternate patterns instead.
  • Anyone with acute pain in the joints or muscles involved, pain is a stop signal, not a soreness signal
  • People with unresolved injuries in the loaded joints, seek clearance from a physical therapist first
  • Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance

Progression path

Once Leg Pull-In feels comfortable with your current load, progress by (a) adding reps until you can complete 12+ per set, (b) increasing resistance by 2.5-5%, (c) moving to harder variations such as single-limb or longer lever versions, and eventually (d) stepping up to intermediate-level movements that train the same muscle.

Safety notes · BODY-ONLY · PULL/COMPOUND · FLOOR

  • On PULL/COMPOUND abdominals work, warm up 5–10 minutes before loading Leg Pull-In; keep first sets light until the path feels automatic.
  • Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
  • Beginners on BODY-ONLY gear: cut volume before cutting form, drop a set rather than rush reps.

Using the leg pull-in

Three ways to put it to work.

  • Train the abdominals 2–3 times a week with 48+ hours between hard sets; pair this with other abdominals movements for balanced development. All abdominals exercises
  • Match the load and rep range to your goal, strength, size, or endurance each call for a different scheme. Strength vs hypertrophy
  • As a compound lift, this trains several muscles at once, anchor your session around it before isolation work. Compound vs isolation

Form before load. If a movement causes sharp or joint pain, stop and substitute a safer alternative, this is general information, not medical or training advice.
