Doctors & research

Doctors are talking about the wall sit.

Cardiologists, clinicians, and a 270-trial review point to the same simple hold.

Independent commentary and published research. Not an endorsement of Sitria.

“I'm a cardiologist. Back against the kitchen wall, knees bent, two minutes. Rest. Four times. In a 100-person randomized trial, doing that 3 days a week for 4 weeks lowered systolic pressure about 9 points more than in people who didn't.”

Inside Sitria

Hold. Release.
See your response.

Your effort has a rhythm. Follow it from a guided hold to your own Rush and Recovery.

Rush & Recovery

Bring the session together: your Squeeze total, your one-minute heart-rate change, and a comparison with last time. One reading is a moment; your sessions over time give it context.

Actual app screens; example readings, not expected results. Sitria is a wellness tool, not a medical measurement or diagnosis.

The exercise

Simple doesn’t mean insignificant.

A 2023 review of 270 trials compared types of exercise. Wall squats came out on top for resting blood pressure.

Most studies were small and supervised. Results vary from person to person.
