Description

  • Exercise switches on waves of genes, proteins and metabolites that boost energy production, repair tissues and stabilize blood sugar, helping you feel more focused and resilient
  • Endurance and strength training activate different molecular pathways, allowing you to choose routines that match your goals for stamina, fat burning or metabolic control
  • Movement improves the signals your bloodstream uses to coordinate immunity, inflammation and stress responses, which supports steadier moods and better overall health
  • Your muscles release tiny molecular "packages" during activity that influence distant organs like your brain and liver, creating whole-body benefits you can't get from sitting still
  • Short, consistent bouts of movement throughout the day reinforce healthier cellular signaling, making it easier to maintain energy, manage weight and stay metabolically flexible
