The Olympions Gym Sand Bag for Core Strength, endurance and Fitness

This is my first sandbag for training, so perhaps I'm not the most knowledgeable person to review an item like this.
The bag arrived in a simple white box with no instructions inside.
Inside the bag itself are 3 inner bags as shown by the retailer.

The online information given by the retailer is very good.
But then falls down with:-
"Three inner bags to easily load or unload your sandbag to your desired weight."
Nowhere had the retailer provided the maximum allowed weight, either online or within the sand bags.

Searching other sand bags on Amazon revealed an "identical" bag.

This has the following information:-
* Comes with 3 loadable filler bags
* Small, Medium, Large bags
* Small Bag can hold upto 5kg
* Medium filler bag can hold 20kg
* Large filler bag can hold 15kg-17kg of sharp sand

So this bag seems to have the maximum capability of up to 42kgs!

I did try to message the retailer via Amazon, but then received a message saying there was a problem with the retailer's email but the retailer did get back to me within 1hr (very prompt).

So for having no instructions within the bag or information on weight - I've taken away 1 star.
And for having an emailing problem with Amazon's messaging system in today's world - I've taken away 1 star. But for their very prompt response, I have returned 1 star!

The retailer has informed me that the sand bag can hold approx 30-35kg sand. But if filled with denser materials (pebbles/grit), it can hold 40-45kg.

What I will do next is load the bag and test it over the next few weeks. If the bag is as durable as it feels, I will update the review and give an extra star back.

See you in a few weeks.

and after a few weeks!

The inner bags and outer bag are all very well made. They feel very robust! I've filled the smaller bags with sand.

Then trained with the inner bags within the large bag.

I found that the bags didn't change as dynamically as I hoped!

So, with the bigger bag, I filled a rubble sack with 20kgs of sand, gaffer taped it, then put that in another rubble sack, gaffer taped it and repeated until I'd used 5 rubble sacks!
Then inserted it within the largest bag!

The problems I had now were; a) the rubble sack slipped from one choke point to the other, but again, not dynamically! This meant the large bag was always heavy on one side when training vigorously! Also, with a 20kgs rubble sack already in the large bag, I couldn't get the other smaller bags inside!

So I took out the rubble sack and replaced it with "loose" pea shingle! 25kgs in total!

Now I have a very dynamic bag that allows me to improve my functional strength! (Around the world being a very good exercise when warmed up)!

There is lots of room for more pea shingle within the bag, but of course overloading it will remove the chaotic movement of the pea shingle defeating the object!

As I use the bag in a tabata style, it doesn't matter at the moment, but I will see if I can add more shingle at a later stage!

Whilst I'm finding the inner bags are redundant for adding weight, I'm finding the bigger two are useful for gripping and maneuvering around as a warmup! Just change hands halfway through for symmetry.

Overall I think this is a well priced and excellent product (£39.95 at time of writing).

And for that, it gets another star!

Having different sized bags was extremely useful for filling to your desired weight. It is very durable and the description accurate. My only criticism is that if not filled to full capacity the weight shifts around a lot, however this is not a problem a bit of extra padding can't fix and in fact can add to the intensity of a workout and really work your core stability muscles!
