Easy Ways to Improve Your Sprint Speed!
Best Sprint Workouts to Make You Faster!
Sprint speed is probably the most measurable way to demonstrate your potential as an athlete. At college camps, the ability to crank out an impressive 40-Yard Dash can be the difference between winning a scholarship or being relegated to walk-on status.
At baseball tryouts and pro days, a good 60-Yard Dash can send a guy’s draft stock through the roof.
Speed is valuable at any level of competitive athletics, so if you want to improve your speed and make yourself more marketable to coaches and scouts, try these drills and exercises.
