Use nitric oxide supplements



Nitric oxide is a compound that acts as a signaling molecule in the vascular system, dilating blood vessels and increasing nutrient and oxygen delivery to all muscle cells. These benefits are crucial for athletic performance since they increase your endurance and strength. There are a number of nitric oxide supplements on the market now, and their main ingredients are arginine and citrulline, which are amino acids that act as potent nitric oxide precursors.
