How to do it
Lying on your back, lift the shoulders and legs off the floor keeping the lower back pressed down and the body in a boat shape. Hold bracing the abs; lower the arms and legs for more difficulty.
Muscles worked
Mainly abdominales. Train it inside a balanced routine to progress safely.
Technical sheet
- Movement pattern
- Core
- Minimum level
- Intermediate
- Technical demand
- Needs coaching
- Fatigue it generates
- Low (0.5 out of 2.2)
- Risk if technique breaks down
- Low
These are the values the generator uses to decide where the exercise goes within the session.
Recommended sets and reps
As an isometric exercise, it is programmed by time: 3–4 sets of 20–45 seconds holding tension without losing position. Increase time under tension before adding difficulty.
Common mistakes to avoid
- Pulling on the neck with your hands and flexing at the hips instead of curling the spine with the abs.
- Using too much weight at the cost of technique and full range of motion.
- Doing reps too fast, without controlling the eccentric (lowering) phase.
How Hollow hold compares with other abs exercises
The catalogue has 14 exercises with abs as the main muscle group. Ranked from least to most fatiguing with the same values the generator uses, Hollow hold is number 8 (tied with one other).
That makes it a good candidate for adding abs sets at the end of a session or in heavy weeks, when you want volume without extra fatigue.
With different equipment, the same movement pattern offers 3 alternatives, such as Cable crunch, Pallof press and Landmine rotation.

Bodyweight. In the trial by Kotarsky et al. (2018), four weeks of progressively harder push-ups significantly improved bench press 1RM, just like training the bench press itself. It is a strength result, not a hypertrophy one, and the condition is the word progressive: the exercise has to keep getting harder.
An isolation exercise. In the trial by Gentil et al. (2015), with untrained young men over ten weeks, the biceps curl and the lat pulldown were equally effective for gaining strength and size in the elbow flexors: isolation is not filler.

Frequently asked questions
What muscles does Hollow hold work?
Hollow hold mainly works the abdominales muscle group, plus synergist and stabilizer muscles depending on the variation.
How many sets of Hollow hold should I do?
Between 3 and 4 sets of 20–45 seconds per session. With isometrics you progress by extending time under tension or adding difficulty (weight, less stable support), not by counting reps.
Is Hollow hold good for building muscle?
Yes. Combined with progressive overload, good technique and enough rest, it's an effective tool to grow abdominales.
