I find that spinach gives me the most energy for cardiovascular endurance such as running 5K. Every time I forget to eat spinach, I feel like I have to struggle through my workout, but when I increase intake of spinach, I fly through my runs. How about you, gentlemen? Which is the superfood that gives you optimal performance? submitted by /u/Artist-in-Residence2
