Bulgarian Bag

How to use
The bag can be used as a free weight in various simple and dynamic movements like pushing, spinning, swinging and rotating, and added to one's body weight to perform jumps, squats, push-ups, pull-ups and power crunches.

Advantages
The Bulgarian Bag strengthens and increases the muscular endurance of the grip, wrists, arms, shoulders, back, legs, and rotational muscles.[13] It also aids in building core musculature, coordination, and improving overall shoulder and joint mobility. Because of its shape, material and construction, Bulgarian Bag can be used to develop quickness and agility in ways which solid iron weights and circuit machines cannot.

Aerobic effectAfter cardiovascular exercise or weight training, the body continues to need oxygen at a higher rate than before the exercise began. High intensity bouts of exercise with the Bulgarian Bag increase metabolic rates higher than traditional weight training and cardiovascular activity because the exercise includes both weight training and fast dynamic movement.
