ATHLEAN-X·Health Fitness & LongevityDo This DAILY for A Flatter Stomach (GUARANTEED)
TL;DR
Train the transverse abdominis daily using the vacuum exercise to cinch the waistline by pulling the belly button toward the spine.
Key Points
- 1.Most people train the wrong ab muscle for a flatter stomach. The rectus abdominis (six-pack) moves the spine vertically, but the transverse abdominis runs horizontally and pulls the waistline inward, reducing its circumference — yet 95% of people never train it.
- 2.The vacuum exercise is the key daily practice. It's a three-step technique: expand the rib cage and lift the sternum, take a deep breath in then exhale all air out, then pull the belly button back toward the spine using the negative pressure created.
- 3.Doing it lying on a bed makes learning easier for beginners. The postural advantage of that position helps people who struggle to engage the transverse abdominis while standing, making it a good morning routine.
- 4.The activation must carry over into all ab exercises. Most people push their belly out during crunches, disengaging the transverse; instead, breathe out and cinch the muscle down first, then perform crunches or planks while holding that contraction.
- 5.RKC-style planks with transverse activation are far more effective than passive planks. Drive elbows backward and toes forward while holding the vacuum for 5-second reps, resetting between reps — this improves core stability, tones the waistline, and supports the lower back.
