Plank
A static core-bracing exercise that builds full-body trunk stability.
Equipment: bodyweight
How to do it
- 1Rest on your forearms and toes, with elbows under your shoulders and body in a straight line.
- 2Brace your core and squeeze your glutes to keep your hips level, avoiding sagging or piking.
- 3Hold the position for time while breathing steadily.
Common mistakes
- Letting the hips sag toward the floor.
- Holding your breath instead of breathing normally through the hold.
Sets & reps by goal
| Goal | Sets | Reps | Rest |
|---|---|---|---|
| Strength | 2-3 | 30-45 sec | 60-90 sec |
| Build muscle | 2-3 | 30-45 sec | 60-90 sec |
| General fitness | 2-3 | 30-45 sec | 45-60 sec |
Ranges reflect the same goal-based logic used by the workout plan tool. These are practical starting ranges rather than exact requirements; actual set count in a generated plan also depends on how often this muscle group appears elsewhere in your week.
Frequently asked questions
Is the Plank safe for beginners?
Generally, yes. The Plank is tagged as beginner-friendly in GetFitArchitect's exercise database, meaning it doesn't demand much prior strength, mobility, or technique. Start with a version you can control throughout, whether that means a lighter weight, an easier variation, or a shorter hold, progress gradually, and stop if something hurts beyond normal muscle effort.
What muscles does the Plank work?
The primary mover is your core. As a core movement, it also involves your hip flexors and lower-back stabilizers.
How do I make the Plank harder as I get stronger?
Add time a few seconds at a time until you can hold about 60 seconds with good form. Beyond that, longer holds add little, so switch to a harder variation (for example, a longer lever or a less stable position) or add load instead.
