Stomach Vacuum is an isolation exercise for the core: one joint works, so it comes after the compound lifts to finish the target muscle. Equipment: bodyweight. Difficulty: beginner, suitable for beginners. It takes 5 steps; the most common mistake is covered in the tip below.
Step-by-step
- Stand tall or get on all fours
- Empty your lungs completely
- Draw your belly button in toward your spine as far as possible
- Hold the vacuum for 10-20 seconds; small breaths are allowed
- Relax, breathe normally, and repeat
Coaching tip
A rare exercise for the deep transversus muscle; it tightens the waistline from the inside.
How to program it
Sets × reps and rest by goal; tempo and controlled reps matter most on isolation work. Start at the bottom of the range in week one; add 2.5–5% when you hit the top with clean form.
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 3 × 6-8 | 120 s |
| Muscle gain | 3 × 10-15 | 75 s |
| Fat loss / conditioning | 3 × 12-15 | 60 s |
