Active mobility of shoulder flexion on the ground
Anterior Deltoid - Lats

- Lying face down on the ground with arms extended.
- Lift them so that they don't touch the ground.
- The ideal would be for your arms to surpass the height of your head, so if you can't, try to achieve it over time.
- Avoid raising the chest off the ground or arching the back.
- For greater difficulty and effectiveness, perform it with pelvic retroversion, so that the lumbar is completely straight.
