NAIZEA Training Sandbag, Heavy Duty Workout Sandbags Fitness Weights Sandbags for Training, Fitness, Lifting, Cross-Training Workouts, Exercise and Military Conditioning

Sandbag arrived on time. First time buying a sandbag and haven’t done a lot of training with them so I ordered a 100lb bag to start off. A 200lb bag arrived. Not one to be discouraged I decided to just roll with it and proceeded to buy 200lbs of sand and fill the bag. Bag holds exactly 200lbs worth of sand. Has a liner already inside of it and has a sturdy zipper and durable seems. Very satisfied with the sandbag.

This thing is great for HIIT or strongman style workouts. Just doing some ground to shoulders for sets or carrying it around for a short distance is a good challenge. If you're new, be sure to look up form videos so you do it right (try Brian Alsruhe - Sandbag Training). As with most things in weightlifting, it's safer to start with a lighter weight to get a feel for it and work your way up. You can add or remove filling from this bag, but it's kind of a pain (even with smaller filler bags). Having a couple different size heavy bags is much more convenient.I filled this bag with ~140 lbs of pea gravel. It could probably hold a little more but it would really be stuffed. (I like pea gravel more than sand because I think it moves better and is easier to get a grip on.) I've also put a few short lengths of chain in the bag to get it up to ~160 lbs. That worked fine but the chains will settle to the bottom of the bag. (Just flip the bag over and do a few sets like that and it'll work back to the other side.) Any metal you put in the bag will get scuffed up, so probably avoid anything that would rust.Personally, I try to avoid dropping the bag from shoulder or chest height. I just lower it quickly but under control down my body back to my lap, then set it down from there. That way there's much less impact on it. It might not look as cool, and it takes a bit more energy, but I want this thing to last a long time. I also prefer to use it on grass or a rubber mat or something like that if possible.I do have to store this bag outside under a roof. I sprayed it with a good canvas waterproofing spray, and it shows no signs of mildew or degradation. I'll repeat the procedure every few months or so.I've lifted weights for several years now, but most objects in real life aren't well balanced with a convenient 1" handle. Strongman implements are great for strength training variety. (But remember, if you want to get bigger and stronger, you must have progressive overload, so you'll need ways to add more weight over time, relative to your strength level.)This bag is also great for HIIT workouts, but don't plan on doing them too often, unless you're "enhanced", or very strong. If you're really doing -high- intensity, you have to give yourself time to recover, or you'll burn yourself out, especially if you're already doing some other form of training.Also, if you aren't training for anything and just want something to toss around for a fun, light workout, you'd probably be better off with a smaller, lighter bag (unless you're very big and/or very strong. It's all relative. I'm 6' ~225 lbs with a few years of weightlifting under my belt, and ~160 lbs is a good challenge, but not max effort for me.)OK, enough rambling. The bag is good. Sandbag training is great. Be smart and have fun.

This thing holds 200lbs of sand and doesn't leave dust or debris. I am 6' 2" and have dropped it repeatedly from shoulder height and all the seems are still tight and totally solid. The fit of the sand is ideal, making it firm (closer to an atlas stone) and easier to pick up off the ground. It allows a little give to compress when carrying also. The only markings on it are "200 lbs" in white letters which is nice if you have multiple black bags. Perfect bag, you will like it.. if you can lift it.

I usually use Cerberus sandbags to train with but needed to purchase one so I could do more sandbag work. This is a very durable bag but takes some getting used to as it has ZERO give. There is absolutely no air in the bag at all and it was challenging to get 150lbs of sand to all fit and close the compartment.

Sandbag broke in less than 3 weeks. It was also too small (I bought the150# and it barely fit 140# of sand. I ended up taking sand out to make it 125#) I have only used it 3x and it's already busted open and leaking sand all over.It was delivered on march 6, 2025. Writing this review march 25, 2025. Didn't even last 3 weeks.

Ok, lots of complaints in the reviews on getting these full. I purchased the 150lb bag. Filled it at a beach while on vacation to keep active. At that time I filled it to the top which ended up being 136. After a few workouts the bag stretched a bit and I easily filled it to 150 and probably could have added more. It is tight at 150 full but I prefer that. More like an atlas stone that way. I’ve dropped it several hundred times at this point without issue. Will update if the bag breaks.

Got the 150lb bag, filled it up with the advertised amount of sand, and started picking it up, thing is sturdy and does what you want it to do. Drop it on concrete all the time and it has *very* minimal fraying/abrasion.

I was just having a full body workout and this only about my 3rd workout really using it and it’s awesome I love it. However, after just a few drops after some carries it’s already busted through. wtf?
