Start faster & run harder
The SKLZ SpeedSac Sprint Trainer puts your opponents behind! Is your speed sometimes a game breaker during a competition? If you ever bump into this, the SKLZ SpeedSac Sprint Trainer is the solution! The use of variable resistance (removable weight bags) when sprinting ensures that the lower body becomes stronger and the explosive force increases. This simply means: start faster and sprint faster!
Determine the weight yourself
The weight bag of SKLZ has three separate weight bags on the inside that can be taken out. This allows you to adjust the total weight to your training yourself. Change the weight in an instant with the inner closure that also protects the loose weight bags in the outer bag. The weight bags are also equipped with handles so that you can use them separately for even more exercises. You can easily tie the SKLZ SpeedSac Sprint Trainer around your waist using the belt attachment. This belt is also adjustable, so that it meets your requirements and you can exercise comfortably.
