Question: Since it's the same material as the Steelbell, can we fill the sandbell with steel shot?
Document: The material is very sturdy. I have only had this for about a month but I can tell it is going to hold up to all the abuse I'm going to put it through. It was easy to fill with regular kid's play sand.
The sandbell is a great tool for working out. I have been using it for a few weeks, 3-4 times per week; with multiple slams and throwing techniques it is not showing any signs of wear. You will need to have a funnel to fill (got mine at home depot) and it takes a little time to fill, but well worth it.
After research- I decided to purchase 2 of the 15lb sandbells (empty) as they are soft material with no hard edges.I filled them to about 9 lbs each. I like them and ordered one more to add a little more weight and balance and to fill up the space in the bag. This is an awesome solution for me and even if it weren't, these bad boys were made to be used like dumb bells. Anyway, highly recommend.
This was a great addition to my work out routine. Very good quality product, and easy to set up. I picked up some play sand at a home depot along with a funnel, which you need to fill it. It comes with a rubber band to close off the tube. Stuck it pack inside the sandbell and it was ready to go. I use it several times a week and so far no sand has leaked out. Very durable.
It came out of the seams on the edge of the sandbell.The 'Ngazzle' (pronounced nozzle, how you fill the sandbell up) seems to keep working its way out of both of the sandbells I bought, I haven't found a solution to fix this yet.Overall: Despite the subtle leaking of dust, I probably will buy more of these. If you use this product in an environment that isn't nitpicky about keeping everything clean all the time, these are a great addition to your workout!
The sandbell is a great product. I purchased the 10lbs and 20lbs version. Basically, it is a heavily stitched stretchy neoprene that you fill sand in. So far, I've been using them for the following exercises:1. One-handed throw and catch - I do this to train my grip strength and it really burns my arm2. Weighted sit up3. Weighted side plank - when doing side planks, I lift the sandbell to form a T.4. Slams5. Side throws6.
I own 2 Sandbells and 1 steelbell and I must say these are GREAT Alternative or Compliment tool for your workout gear!!! The shifting of the sand really trigger ALL THE Muscles for a real good workout!!! Highly recommended! !
As a 25 year veteran of the fitness industry. I am constantly looking at ways to challenge my clients in a functional way versus the &#34;standard American workout&#34;. The instability and give on a sandbell adds that challenge to the nervousness system.
I got this for my training. It is very useful as i can bring it around easily. This sandbell can be use indoor or outdoor. I used it a lot of balancing exercise. But after just a couple of usage my sandbell start to leak. I'm not sure what cause the leak till i found a cut at the back of sandbell which i'm not sure how the cut get there.
Made very well. No need to worry about leaks when slamming them. I found them easy to fill and use.
