SKLZ Zandzak Super Sandbag - Variabele gewichtstas trainingsapparaat, zwart, één maat

Ordered this sandbag a couple of weeks ago, received it promptly and so far I am very happy with it.So let me first address the two main issues listed by other reviewers.1. Maximum weight in the weight bags and leakage: When something refers to "sand", they usually mean real sand, as in construction or last resort - beach sand. It would have never occurred to me to use child play sand or moon sand or whatnot, as first they are not exactly sand, and secondly, they are more expensive anyways. Used construction sand and filled each bag to slightly less than 10lbs, but in the end when all weight bags were fitted inside the sandbag, the total weight was exactly40lbs/18kg, as indicated on the box. So, yeah - you can do it. And so far - no sand leaks, although I threw the sandbag around plenty of times.2. Fitting the weight bags inside the sandbag - it is difficult at first, I placed the in a zig-zag manner with the weight bags enclosures towards the centre of the bag and after a few minutes of struggle I zipped it up. However after using it a few days, the sand settled (or rather compressed) and now there is even room to spare or even add more stuff inside - I am pretty sure I can fit a fifth weight bag inside. I am planning to put some cloth inside to make it bulkier and more gentle to the shoulders when I do shoulder press, power clean, etc. I think that removing the weight bags is even possible during training, although I wouldn't do that myself as the weight is Ok as it is for me.Now, two minor worries - first, it is a bit light for some exercises - I would've wished it to be a tad larger and carry more weight - perhaps up to 60-70lbs, but for its compact size it is surprisingly heavy. Secondly, when doing the swing (sort of like kettlebell swing) I can hear one of the handles giving away very slightly if I put more explosiveness in the motion - it has not torn up yet but it feels like a possibility. Other than that, it is very useful and decent quality sandbag I am hope I will use it for at least a few years, as it allows some exercises that are quite dangerous with regular dumbbells or kettlebells. Perhaps a lady version for my wife with less total weight would be a good future idea (I know we can use only two weight bags but a smaller version would be better, I guess).

Buena calidad, rellené los costales de arena. Peso de 40 lbs total. Sirve para hacer ejercicio, de buen tamaño, cómoda por la variedad de agarraderas. De buena calidad, resistente, fácil de limpiar por fuera. Por dentro por el uso la arena demasiado fina sale pero no sale por la lona o costal principal. Solo de los costales interiores pero es muy poca

Great addition to the gym. After a few months of use the handles and material seems to be holding up. I would recommend this brand.Cheers

Since buying this item I've not had to use half of my the weights that I bought, the bags very strong and quite heavy when all four bags are full with sand. You can do loads of seperate exercises with it not just the ones that come to mind, but go online and have a look ands theres loads of youtube videos.Im faster stronger fitter and have more time to dedicate to my workouts because the bags so versatile.

Bonne qualité/prix...rempli de 16 kgs de petits cailloux divisés dans les 4 sacs, il fait le boulot, semble solide.Parfait pour moi.
