DEMON SLED™, LLC is an Austin based firm that has developed a revolutionary athletic training sled that helps coaches amateur/professional athletes and trainers, promote proper explosive form and improved acceleration, speed and power! The Demon Sled is configurable for adding weights in some embodiment's to increase friction and provide weight-training, by lifting portions of the sled. The problem: Athletes aren't achieving their acceleration development goals no matter how much time, money and effort they spend. It’s not due to a lack of speed trainers, coaches, training programs, equipment or athletic trainers. The reason why athletes don’t see measurable results are because those other “sleds” aren't designed to work in conjunction with proper running form and improve acceleration. Here at Demon Sled, we've conquered that problem by integrating our unique, patent pending Demon Sled that will promote explosive power and acceleration into one sled. The key elements include forward motion training, strength conditioning, improved acceleration and power built into a customized sled made available to coaches, athletes and professionals alike.
