Distance: Do as many repetitions as you can in a 10 yard span. Once you have gone 10 yards, return doing the same thing for a total of 20 yards.
High Knees: High knees is an aggressive warm up exercise that simulates sprinting intensity. Two very important points to keep in mind are heel placement and balance. First, bring your heel straight up under your body, which brings the knee up; we want to avoid marching. Second, make sure to keep your balance leaned slightly forward with your weight over your toes and pump your arms with a ninety-degree angle, working on proper sprinting technique.
