Caffeine contains adenosine, a pain-relieving substance similar to over-the-counter pain medications. Drinking caffeine before working out may help reduce muscle soreness and can, unsurprisingly, ease fatigue. Also, research shows that combining caffeine with other anti-inflammatories may provide even better pain-relief. That said, caffeine is a diuretic, so it is important to keep drinking enough water during or after the workout.
