Swapped crunches for planks and bird-dogs — my back feels so much better. Thanks for the anti-crunch approach!

What your core is actually for
Your core is a 360-degree system — front, sides and back — designed to resist movement, not produce it. That means the best core exercises make you hold position under tension, not crunch through reps.
The anti-crunch core menu
- Plank — the anti-extension king.
- Bird-dog — anti-rotation with limb movement.
- Glute bridge — posterior core and hip strength.
- Dead bug — deep core control without spinal loading.
A 12-minute core circuit
| Move | Work | Rest | Rounds |
|---|---|---|---|
| Plank | 30 sec | 15 sec | 3 |
| Bird-dog | 10/side | 15 sec | 3 |
| Glute bridge | 15 reps | 15 sec | 3 |
| Dead bug | 10/side | 15 sec | 3 |
How often to train your core
Your core works in every exercise you do, so 2-3 dedicated core sessions per week is plenty. You can also sprinkle 5 minutes of core work onto the end of any workout.
Questions
Frequently Asked Questions
Will core training give me visible abs?
Core training builds the muscle; reducing body fat reveals it. Both matter — training without diet change won’t show, and diet without training won’t build much either.
Are planks better than crunches?
For most people, yes. Planks and anti-rotation moves build functional stability with far less spinal stress than crunches.
