The SPARROWBAG® is both an innovative piece of sport equipment and at the same time a comprehensive training method. SPARROWBAG® exercises are suitable for simultaneous development of the whole body’s musculature. Impressive results can be achieved with the simple exercises even in a short period of time. Exercises can be performed anytime, anywhere, individually or in groups. It is recommended for anyone from the age of 10.

 

For beginners - Due to the bag’s safe usage, it is great equipment for those users to develop their general muscles and fitness level. To facilitate this, individual training guidelines can be downloaded free of charge directly from the website.

 

Those who like training in groups can meet with their bags at the gym or at other fitness oriented events or aerobic activities.

 

For professional athletes it can be incorporated into their training program as a supplementary accessory or as an independent workout. In addition to the basic exercises, sport-specific complementary exercises can be downloaded from the website.

The SPARROWBAG® has been designed primarily to involve and exercise those muscles that are not stimulated during a typical training session at the gym. The SPARROWBAG® fits the body ergonomically. Furthermore, because there are no handles or other elements facilitating its grasp and due to the sand content constantly changing its shape, it forces the development of otherwise neglected muscles. Since this equipment is not easy to hold, it prevents the movement of weights which are disproportionately heavier than the hand or arm’s strength, as a result, the risk of overload is eliminated. Its shape, material and sand filling make it particularly safe.

 

The 12 basic exercises are capable of stimulating the entire body. We can increase training intensity at will by repeating the number of sets for each exercise, or by repeating entire exercise series as well as by adjusting the weight of the SPARROWBAG® itself. In this way we can attain a highly varied training program, preventing our body from becoming overly adapted to a specific level of physical demand.

The idea of the SPARROWBAG® can be traced back to the early 90’s when a group of selected decathlon athletes of the European Continental team were preparing at the Brigham Young University (BYU), Provo City (Utah, USA) for a 9-week foundation-building training camp. At that time, the coach in charge of strength conditioning, along with the athletes – unaware of the training facilities offered by the university – decided to incorporate new, simple but effective elements into the training program.

 

One of these elements was a bag filled with sand, which served primarily as a substitute for the possible lack of weight training equipment. The bag was made from a cut out piece of a pair of jeans and it was filled with sand ”borrowed” from the long-jump area.

 

During these 9 weeks, the method resulted in unexpected improvements and this is what substantiated the tradition of the bag. The bag progressively found its place among the training programs of other sports disciplines where a well-balanced development of muscles is fundamental to the physical culture of the given sport.
