Yes4All X-Sandbag Core Training System

This item lasted less than 10 workouts before the whole side ripped open, rendering it totally useless. It was never thrown or dropped. Of course, it ripped a week after its eligibility for return (30 days). Don't bother with this useless piece of garbage. If you do buy it, be sure to never pick it up or try to use it for exercise. Maybe use it for, say, a doorstop or perhaps a paperweight. Just be sure it's a really, really light door or a very small stack of paper.**Update** I contacted the company 10 days ago through Amazon, and I have had no response. Zero stars for their crappy product, zero stars for their customer service.

It's actually decent if you want some extra weights for various exercises or to load up your pack for rucking. My only grip is that the 10lbs bags don't really hold up to 10lbs. Fully packed i was able to get it to be about 8.2 lbs at the most. Which is not entirely too bad...but if you consider that 2x bags will only get you about 16 lbs rather than 20 lbs, and with 3x only getting 24 lbs rather than 30lbs, then yeah it's kinda a downer. But still, weight is weight and its convenient to have around for the price. I bought the one with 5 bags so technically i can pack it up to about 40lbs, rather than the 50lbs that i was expecting (not that i plan on hauling around 50lbs for rucking...not in the Marines anymore, heh).Instead of actually putting sand directly into the bag itself, i would recommend putting the sand into a plastic zip-lock type bag, then putting those into the main bags to prevent any tears or leakage. I was able to fit 2 of the zip-lock quart sized bags into 1 weight bag. It'll be snugged but i'll fit.Other than the weight issue for the bags, i like it. Its clean, compact and does the job of what i need.

This is not a brand name core training system (well... not in the US, at least), which means I had money left over to spend on other things. It's the only sandbag system which allowed quick 10# changes without having to do higher math. My son has been training himself to carry heavier loads using the individual sandbags to add weight in small increments. It must be working, as he is now hiking steep trails with a 80#+ pack. Unfortunately, I cannot speak to the durability of the outer bag, because the system isn't being used for its intended purposes. The individual sandbags are durable and stout, and they hold their sandy contents very well (no leakage/spillage). The only reason I didn't give it a five star rating is because I can't make sense of the brand name (Yes4All).

So I looked at many different sandbags for my kids to start working out. I read other reviews and took some tips on duct taping the inner bags to make sure there is no leaks and it worked. Once I got all the bags filled (about 8 lbs each), I taped them and placed them in the bag. Not that hard to get all 5 bags in, but when I picked it up the seam ripped before I even used it. I was very disappointed. I will probably spend a little more and buy better quality bag.

For the money, it's pretty sturdy. I filled the included bags, but they don't get as heavy as advertised. I had to add a couple extra inserts to get the desired weight. This in turn makes the bag fairly full, so the sand doesn't move around at all. Is this good or bad?... up to you.

Can't wait to try this out bag was a bit smaller than I thought but none the less it's a great workout I used ziplock bags to secure the sand in but all the fillers won't fit in the bag ( probably from the ziplock bags) didn't feel safe putting the sand in the filer only because it's Velcro only (Velcro does seem strong but didn't want to take a chance I will try it like this first and if it doesn't work out I will just use the sand in the filler without the ziplock or some sort of protection.

I actually got this a long time ago but didn't start using it until about a month ago, I was using the ultimate sandbag instead with only 25lbs, finally I graduated to this one thinking I can put 50lbs of sand in it, well not even a month of being consistent with it, the handles stitching is falling apart. Doubt I can return it since I've had it for so long even though it's barely used. Oh well

Rubber handles and outside bag are the sturdiest parts of this product. Zipper is weak, individual sandbags break, and sand will leak out of the corners into larger bag. Fix these and you have a great product for workout with a convenient shape for carrying on back or shoulder(s).
