Kostas Martakis: Menegaki's advice for camera confidence

Kostas Martakis revealed advice Eleni Menegaki gave him to appear more confident on television. The advice concerned body posture during interviews.
Specifically, Eleni Menegaki suggested he place a pillow behind his back or low on the seat when sitting in an armchair, to maintain a straighter posture and avoid appearing 'slumped' or 'hanging'. This, according to Kostas Martakis, helps him appear more 'ready and prepared' in front of the camera.
