Why visualizing release grip heavier body resistance?

I have found myself feeling heavier and more weighted after a session in which I am visualizing releasing pounds more strongly. It is a kind of ironic physical feeling like my body is surely resisting by gripping tighter since my mind is attempting to make it release. The blunt style is counterproductive. It appears my body is not responding to commands but to a more accepting energy, which I am finding very hard to produce. Name: Divya DOB: 14th June 1998 Time: 7:30 AM Location: Coimbatore
