I was looking for this comment! Not a doctor, but as I understand it muscle is roughly equivalent to fat as far as your heart’s workload is concerned. I thought I also read that muscle movement helps with blood return.

Muscle movement is also necessary for the limbic system to function.

Limbic system is unrelated to muscle movement.

Movement is required for the lymphatic system to function, excess muscle volume doesn’t help.
