In this short fitness coaching video, the speaker warns that a weak core is the worst thing for anyone who sits all day or neglects core training. He explains that crunches and sit-ups only teach abdominal flexion and do not provide spinal support, leading to back tightness, collapsed posture, and reduced performance. The core’s primary role is stability, protecting the spine and transferring force. To address this, he recommends functional stability exercises such as anti‑rotation holds, loaded carries, and controlled leg raises performed slowly, emphasizing training for function rather than just fatigue. He invites viewers to DM him for personalized core‑strength guidance.

The worst possible thing you could ever do for yourself is having a weak core, especially if you sit all day doing work or really just never properly training it. And no, crunches and sit-ups don't necessarily fix that. They just teach your abs to flex without supporting your spine. Lock in and peak gain. Your core's primary job is stability, resisting movement, protecting your back, and properly transferring force. That's why you feel that back tightness doing lifts. Yes, a weak core will cause that, and also why your posture collapses by the end of the day. Exactly why I strongly recommend doing things like anti-rotation holds, Loaded carries. Yes, real slow too, actually. Controlled leg raises. Those are really good for you. These reteach your core to support you, not just burn. Train for function, not just fatigue, and your entire body, it starts working a lot better. So for ways to improve and strengthen your core, just DM me, coach.
