Habits Rewrite Your Genes' Impact, Not Their Code
Genetics is mostly fixed. Epigenetics is dynamic. You cannot change the DNA you inherited. But you can influence how that DNA is expressed through the signals you repeat every day: stress, sleep, food, movement, connection, and recovery. Chronic stress can push biology toward inflammation. Consistent...
Avoid NSAIDs Before Workouts; They Hinder Recovery
NSAIDs can blunt many healing responses and beneficial adaptations to exercise... They don't heal much... use them sparingly and wisely. Try never to take them before a run or ride. https://t.co/7kAEvmWtkF
