How to Do the Sphinx
- Lie face down on the floor with your forearms flat against it, elbows lined up directly under your shoulders.
- Brace your core and lift your chest off the ground, keeping your forearms and toes on the floor.
- Hold this position for a few seconds, keeping your neck in a neutral position.
- Slowly lower your chest back down to the starting position.
- Repeat for your planned rep target, maintaining clean technique and steady breathing on every repetition.
Quick Exercise Facts
Practice and progression
Choose a short set of controlled repetitions or a manageable hold, following this movement's setup. End the set when you lose the demonstrated position. Build control before increasing repetitions, duration or resistance; holds, carries and moving drills need different prescriptions.
Technique & Form Tips
Use the movement steps and demonstration for this particular exercise. Match the body position, support points and direction of movement before adding resistance or speed. Holds, cardio movements and lifting exercises need different execution cues.
Common Mistakes to Avoid
- Erratic tempo: Avoid rushing; perform each phase of the movement with deliberate, steady control.
- Copying another exercise setup: Follow this exercise's demonstrated support and body position rather than applying an unrelated lifting cue.
- Losing support: Keep the demonstrated footing, grip or support secure throughout the movement.
How to Breathe During This Exercise
Breathe steadily throughout the movement.

FAQ
- What should I check before the Sphinx?
- Check which parts of the body are supported and which parts move in this demonstration. Back and trunk movements use different positions; follow the specific steps rather than copying another exercise.
- What equipment do I need for the Sphinx?
- You do the Sphinx with no equipment — just body weight. Make sure your equipment is set up safely before starting. If you work out at home or have limited gear, check out our alternative exercises below.
- What form mistake should I watch for on the Sphinx?
- One mistake to watch for is erratic tempo: Avoid rushing; perform each phase of the movement with deliberate, steady control.. Use a comfortable range and a controlled return; reduce the load if you cannot maintain the demonstrated setup.
- How many sets and reps should I perform on the Sphinx?
- Use a short set of controlled repetitions, or a manageable hold when the movement is static. Stop when you cannot maintain the demonstrated position. Build control before adding duration, repetitions or resistance; the appropriate amount depends on the exercise and your experience.
