How to perform Stomach Vacuum
- To begin, stand straight with your feet shoulder width apart from each other. Place your hands on your hips. This is the starting position.
- Now slowly inhale as much air as possible and then start to exhale as much as possible while bringing your stomach in as much as possible and hold this position. Try to visualize your navel touching your backbone.
- One isometric contraction is around 20 seconds. During the 20 second hold, try to breathe normally. Then inhale and bring your stomach back to the starting position.
- Once you have practiced this exercise, try to perform this exercise for longer than 20 seconds. Tip: You can work your way up to 40-60 seconds.
- Repeat for the recommended amount of sets.
Muscles worked
- Core (primary): braces the trunk and resists twisting to protect the spine.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
As a mobility drill, hold each position for 20–40 seconds (or move slowly for reps) rather than training it to a heavy load.
Form tips
- Brace as if about to take a light punch and breathe shallowly — don't hold your breath for the whole set.
- Own the largest range you can control with clean form before you chase extra reps.
- Ease in until you feel mild tension, never pain, and breathe out as you sink a little deeper.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Cranking with the hip flexors or neck instead of moving from the trunk.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Bouncing into the stretch instead of holding it steadily.
