Resistance sled is a sled-like training tool that can be stacked with heavy weights (usually barbell weight plates), in order to increase physical fitness and speed during exercise, and can mobilize almost the whole body muscle groups during training, with great exertion and simple movements, making it a priority for strength training. The sled is made of durable steel tubing, with very little welded construction, very strong and durable. It can also be pushed and pulled on multiple surfaces with accessories and has a flat bottom, allowing training on a variety of surfaces.
