About this routine
Five floor moves for your abs and the muscles that hold your spine steady: dead bug, bicycle crunch, bird dog, lying leg raise and a plank. Two sets of each, and you need only a mat.
For beginners and for lifters who want a short core session after training. If your lower back gets sore easily, start with the Core and Posture session below, which swaps the crunch and leg raise for a Superman and a hollow body tuck.

Rest and progress
Rest between sets
- Rest 30 to 60 seconds between sets. Core sets are short, so you recover quickly.
- Do both sets of one move before going to the next.
How to progress
- Weeks 1 and 2: learn the moves. Keep your stomach tight, as if someone is about to poke it, and stop if you feel it in your lower back.
- Add reps or seconds. When every set reaches the top of its range, slow the reps down or hold each one for a second.
- When the 10 minute version feels easy, switch to Core and Posture below, which has 3 sets of each move.
Swaps
- Lying leg raise hurts your lower back
- Bend your knees, or only lower your legs as far as you can keep your back flat.
- Front plank too hard
- Plank on your knees, and add seconds until you can hold the full version.
- Bicycle crunch strains your neck
- Keep your hands light behind your head and move from your stomach, or swap it for a second round of dead bugs.
- Want it harder
- Hollow body tuck, from the Core and Posture session below.
The longer version: Core and Posture
Three sets of five moves, including the Superman for your lower back and a hollow body tuck. Good on its own day.

Questions
Will an ab workout burn belly fat?
Not on its own. In one study, 6 weeks of ab exercises did not reduce belly fat, though it did improve ab endurance. Nutrition is the other big factor.
How long does this ab workout take?
About 10 minutes, plus a short warm-up. Core and Posture takes about twice as long.
How often should I train abs?
Three times a week with a day off in between, as in the schedule above. If your core is still sore, take another day.
Can I do this after a gym workout?
Yes. It is short enough to add at the end of a strength session. Do it after your main lifts, not before, so your core is fresh for those.
Do I need any equipment?
No. A mat or a carpet makes the floor moves more comfortable.

Six weeks of ab exercises alone did not reduce belly fat, but it did improve ab endurance. That is why this page makes no fat loss promise.
-
Adults should do muscle-strengthening work for all major muscle groups on 2 or more days a week. Core work is one part of that, not the whole of it.
-
Large muscles and multi-joint lifts go before small muscles and single-joint work. That is why core work goes at the end of a gym session.
