What the Bottoms Up Data Reveals · DOC · PULL/COMPOUND
Bottoms Up opens on force profile: a PULL compound pattern for abdominals on just bodyweight, force direction is the first filter on this floor-level record.
3 steps sit in the lower third (< 4), a thin upstream record where taxonomy badges carry most of the page identity.
Bottoms Up is classified as a beginner-level compound movement with a pull force profile, primarily training the Abdominals. The canonical form requires just bodyweight in the strength category. Within the abdominals cohort, 9 catalogued movements share the primary target; no alternate-equipment variations are catalogued yet.
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.

Bottoms Up catalog footprint
Among 93 exercises whose primary muscle is abdominals, Bottoms Up ranks #12 by catalogued variation count (0 listed heres). The upstream file attaches 2 images to this slug. See the step-count ranking for abdominals for peer documentation depth.
Muscles worked
According to the Free Exercise DB classification, Bottoms Up trains the abdominals as the prime mover and no catalogued secondary muscles. The source classifies muscles as primary or secondary, it does not measure activation, so we show involvement, not percentages.
Source: Free Exercise DB primary/secondary muscle classification. Involvement, not measured activation, actual recruitment varies by load and form.
Intensity context
For reference, here is where common activities sit on the MET intensity scale. Bottoms Up 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 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
- Begin by lying on your back on the ground. Your legs should be straight and your arms at your side. This will be your starting position.
- To perform the movement, tuck the knees toward your chest by flexing the hips and knees. Following this, extend your legs directly above you so that they are perpendicular to the ground. Rotate and elevate your pelvis to raise your glutes from the floor.
- After a brief pause, return to the starting position.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Bottoms Up 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 Bottoms Up is what most reliably separates effective reps from wasted ones.
- Treating a compound lift like an isolation movement - Bottoms Up 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 Bottoms Up - 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, PlainExercise lists 0 catalogued variations for Bottoms Up; browse 8 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 Bottoms Up 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.
See the Progression guide for a full framework on when to advance, and the Compound vs Isolation guide to decide when to prioritize this movement in your program.
Safety notes · BODY-ONLY · PULL/COMPOUND · FLOOR
- On PULL/COMPOUND abdominals work, warm up 5–10 minutes before loading Bottoms Up; 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.
- General information only. Consult a physician or certified trainer before starting any new exercise program.

Using the bottoms up
A beginner compound movement for the abdominals - here's how 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.
