I Tested 30 Ab Exercises - You Only Need These 2
Main summary
Key takeaways
Key strategies & takeaways (abs training)
-
Choose exercises that hit “three boxes”
- Progressive overload: you can add weight over time so your abs grow like any other muscle.
- Deep stretch + tension: the movement creates meaningful tension while your abs are lengthened.
- Limit hip-flexor takeover: hip flexors shouldn’t do most of the work (measured with EMG on upper abs, lower abs, and hip flexors).
-
Use form cues that keep the abs doing the work
- Bring the rib cage toward the pelvis (curl into a C-shape).
- Curl / pelvic tilt intentionally (think “curl your pelvis / tailbone up”).
- Don’t cheat with arms or neck strain.
- Avoid swinging / instability—stability often improves how much the abs are actually targeted.
-
Train both upper and lower abs (even if you can’t truly isolate them)
- You can’t fully isolate upper vs. lower abs like biceps, but certain movements emphasize one region.
- The video proposes color-coding based on EMG:
- Purple: emphasizes upper abs
- Green: emphasizes lower abs
- Red: hits everything fairly equally
-
Planks / holds aren’t automatically “bad,” but they often miss the main growth requirements
- Regular planks: low on full range-of-motion / stretch, and harder to progressively overload (unless someone loads you).
- Variations can improve activation (e.g., RKC plank), but still come with downsides.
-
Isometrics can work—especially in stretched positions
- Garhammer hold was highlighted as showing strong tension in a stretched position.
- Some evidence was cited that stretched isometrics may build muscle similarly to full ROM—though progression can be harder.
Best-of lists (what the video recommends)
Best for beginners (2 picks)
- Face-away lat pull-down cable crunch (upper abs focus)
- Reverse crunch + ab mat / rolled towel under lower back (lower abs focus)
- The mat/towel helps fix the “floor/bench limits stretch” problem by allowing deeper spinal extension at the bottom.
Best for advanced (2 picks)
- Still the face-away lat pull-down cable crunch (upper abs focus)
- Garhammer raises (lower abs focus)
Practical “how-to” equipment tips
- Use an ab mat or rolled towel under the lower back to:
- Increase bottom-of-rep stretch (a recurring limiter on floor/bench variations).
- Use assistance to enable perfect abs mechanics
- Assisted lat pull-down crunch helped someone who couldn’t do unassisted reps still perform the movement with good control.
