Ordered carrier SC500-AF, WOW, what a well built product! I've been a welder/fabricator for over 47 years using all forms of welding processes. I know quality workmanship, this has well designed construction and welding assembly.
But exercise also stimulates brain regions that are involved in memory function to release a chemical called brain-derived neurotrophic factor (BDNF). BDNF rewires memory circuits so they work better.
The effects of this group of chemicals include stimulation of the central nervous system (CNS), diuresis, stimulation of cardiac muscle and relaxation of smooth muscle. Caffeine initially stimulates the CNS at the level of the cerebral cortex and medulla and only later stimulates the spinal cord (at higher doses).
