When it comes to running and sprinting, the so-called weight bags can help you improve your performance. At Frank you are at the right address if you are looking for weight bags. By using weight bags you train on the development of muscle strength, the speed of your step movement and the length of your steps. This is therefore primarily an ideal tool for improving sprints.
In addition, Frank also offers weight bags with handy handles that you can take anywhere by taking the sand filling out. This means that you can develop explosive muscle strength anywhere by putting sand in place. All these weight bags are meant to make an exercise more intensive and to increase the training ceiling.
