Hey fellas, I'm incorporating eight 40yrd dashes for at least 4 times a week to my westside routine. I'm getting ready for the spring camp of my local arena football team. I am still concentrating heavily on my routine and I don't want to compromise it, however, I must start working on my speed again. What days would you advise for me to do these? Also, if you know of any particular excecise that would help my speed and or agility, I would greatly appreciate it.
