SPEEDSAC vs. THE COMPETITION. YOU BE THE JUDGE.
SpeedSac vs. the Metal Sled
The metal sled was the inspiration for the Speedsac. The Speedsac functions in the same capacity as the original model, but in a safer, more convenient, and more user friendly manner. It stops when you stop. There is no annoying rattle and the speedsac remains on the ground at all times. If performing loaded sprint training on an incline there is no fear of running/slipping into the Speedsac as it is composed of low density, pliable materials. The Speedsac’s make-up allows for it to be used on multiple surfaces without causing damage and is preferred for astro-turf surfaces. The Speedsac won’t rust and 12 Speedsacs fits in the same storage place as 1 metal sled. The most important dynamic is the Speedsac starts off at less than 1lb and could be loaded with the proper amount of weight (10-15% of ones body weight) to be used by younger athletes, where if they were to use the heavier metal sled it would change the way they run and therefore make the exercise counterproductive if not out right detrimental to their health.
SpeedSac vs. the Parachute
The parachute, while providing resistance, gives you an inconsitent immeasurable amount that often time does nothing to enhance ones ability to come out the gate. After a few steps the parachute will open thus neglecting the key component (which is the start) to lowering ones sprint time. Often times younger athletes do not have the capacity to generate enough velocity to even open the parachute which can be frustrating and disappointing. The Speedsac addresses the start first and allows for a consistent measureable resistance to be pulled for the duration of your sprint. This allows you to properly calculate and chart your progress. Younger athletes’ rear and back side muscles are developed to keep a balance with their front side muscles which have already been advanced through their participation in their respective sports. This balance is a preventative measure to remain injury free during training while creating more horsepower to stay fresher longer.
SpeedSac vs. the Bungee Cord/Resistance Bands
The people who benefit from using the bungee cord/resistance bands are usually the already fully developed athlete who has progressed enough with their training to master this inconsistent constant resistance. The person or entity used as the anchor has to be or should be a trained professional. When the anchor is a novice you leave a lot of room for injury especially dealing with younger athletes whose resistance muscles and coordination are still developing. This style of training while extremely taxing may yield little to no improvement with a high risk of injury. Do not mistake activity for achievement! The simplicity of using a dead weight that is constant in measurement like the Speedsac assures yourself of a safe way to get the results for which you are looking.
