Eccentric Leg Exercises
Dr. Berg explains that the core problem in inner thigh fat is a shrunken, fibrotic muscle that can't burn the surrounding fat. Eccentric exercises directly address this by forcing the muscle to adapt and get bigger. He notes that even the simple act of walking slowly downhill is an eccentric movement for the quads and is therapeutic. He stresses that the soreness is part of the process and that rest days are when the actual rebuilding occurs, not during the workout. The muscle's demand for energy during these exercises, combined with later fasting, creates a local 'vacuum effect' that sucks fat out of the tissue.
Eccentric loading creates micro-tears in muscle fibers, which activates satellite cells (muscle stem cells) and stimulates mitochondrial biogenesis. The lengthening under tension sends a potent growth signal to the muscle, reversing the atrophy and reclaiming space from fat and scar tissue.
These exercises are slow and you're lengthening the muscle... the strongest stimulus of muscle activation. So we can really start building these muscles up by doing this type of exercise.
