The fastest feet run on Fridays We love getting extra intent out of sprint reps by adding layers like parter races and tennis ball chases. Don’t have to reinvent the wheel to get higher outputs from competitive athletes like our stsebslax crew. This first race was obvious—but their rematch? Who ya got? #fastfeetfriday #acceleration #athletedevelopment #speeddevelopment #sportsperformance #lacrosse
