¡HOLA! 21‑Day Full Body Core Challenge Adds Lateral Plank Crunch and Dead‑Bug Exercises

The "¡HOLA!" 21‑day full‑body challenge, designed by trainer Andrea Landes of KO URBAN DETOX CENTER, progresses participants through a structured core‑strength program. After completing an initial mobility phase, the first week focuses on the abdomen and core, introducing two new moves.

The lateral plank with a crunch engages the obliques and transverse abdominis while also recruiting glutes and shoulders for stability. The supine "dead‑bug" alternates opposite arm and leg extensions to activate deep abdominal muscles and protect the lumbar spine. Both exercises are promoted for improved posture, lumbar protection, calorie burn and overall functional strength.

The routine provides step‑by‑step instructions, emphasizes controlled motion over speed, and suggests modifications for safety. Consistent practice is recommended to see results in core stability and lower‑back health.
