Sandbag training has a lot in common with kettlebells in regards to their ability to challenge strength, endurance, and synergistic movements . The awkward nature of our bag is constantly forcing the lifter to maneuver and adjust to the shifting weight. This causes the body to use more muscle groups than with conventional barbell or dumbell movements.
Some of the reasons why you should train with sandbags are:
Bags are rated to 40KG and do not come with filling, we reccomend a rounded pea gravel for longevity of the bag.

I liked these sandbags my only comment is that if you are using pea gravel use the one that are indeed ROUNDED. I got pea gravel however it was not rounded and with all the throwing and hard dropping of the sandbag, the sharp edges of the gravel eventually cut a small hole in the filler bags. I just used duck tape to patch but in retrospect I should have used the actual rounded pea gravel (without sharp edges) or sand.
Other than that great product for the price.
