If it is true that minimal muscle damage is done while doing a B Strong session without heavy weights, How do people get bigger and/or stronger with the B Strong?Updated a year ago

This is one facet of the beauty of the B Strong Training System.  By restricting blood flow in and out of an extremity, it disturbs the homeostasis normally found in muscle and produces the stimuli for adaption with minimal damage to the working muscle.  That “disturbance of homeostasis” (generally, increased metabolic acid and decreased oxygen in the muscle and associated metabolic by-products) stimulates development/adaptation locally, as well as, stimulate nerve fibers (Group III and IV afferent fibers, linked to metabo-receptors) to send a signal to the brain to release a systemic anabolic response.  Generally, light weights and concentric exercises do not damage muscle fibers, while heavy weights and eccentric exercise can and does damage muscle. The more damage done to a muscle, the longer it takes to repair that damage before moving on to build bigger and stronger muscles.
