“Lower abs” aren't a separate muscle — they're the lower portion of the rectus abdominis. But training it with hip-flexion and pelvic-tilt movements does change how hard that region works, and many people simply store more fat there. So the plan is the same two-part system, with smarter exercise choice.
Why lower abs show last
Fat distribution is largely genetic and hormonal; the lower belly is a common last-to-go area for both men and women. That's normal. Keep the deficit going — the timeline calculator helps you stay patient with real numbers.
The 6 best lower-ab exercises
- Reverse crunch — curl the pelvis, don't swing the legs. 3×12–15.
- Dead bug — anti-extension with the lower back pinned. 3×8 per side.
- Hollow body hold — shorten the lever until your back stays down. 3×20–40s.
- Lying leg raise — stop before your back arches. 3×10–12.
- Hanging knee raise → hanging leg raise — the progression that builds real lower-ab strength. 3×8–12.
- Ab-wheel rollout — brutal anti-extension; start kneeling. 3×6–10.
10-minute lower-abs workout
| Exercise | Work | Rest |
|---|---|---|
| Reverse crunch | 40s | 20s |
| Dead bug | 40s | 20s |
| Flutter kicks | 30s | 30s |
| Hollow body hold | 30s | 30s |
| Lying leg raise | 40s | 20s |

The one form cue that matters: posterior pelvic tilt
At the top of every lower-ab rep, tuck your tailbone slightly (flatten your lower back). Without that tilt, leg raises turn into a hip-flexor exercise and your lower back takes the strain.
Frequently asked questions
Can you target lower belly fat?
No — spot reduction doesn't work. You can target the lower ab muscle, but fat comes off according to your overall deficit and genetics.
Why do leg raises hurt my lower back?
Usually the pelvis tips forward and your back arches. Bend the knees, reduce the range, or switch to reverse crunches and dead bugs until you can hold a posterior tilt.
