These foam rollers are an amazing way to achieve a full body stretch before any workout. They massage and provide an even amount of pressure to the body, allowing one to dynamically warm up and loosen up their bodies for physical activitiy. Before using this, I would sometimes have muscle pain or soreness after working out due to lack of proper stretching. However, after using this foam roller for a full body stretch before all workouts (it only takes several minutes), I have found that my body heals more quickly and efficiently after even the most strenuous workouts. This should be a necessary addition to everyone's workout warm-up routine in order to prevent injury and properly stretch out.
