## Questions & Answers

**Q: Thoughts on using two of these bags for substituting plate weights for bench press?**
A: Its not a substitute.  The sand bag, overall, works more body parts.  Example, squats...the way I do squats with the bag is one of two ways.  The traditional way ..pick it up off the floor and place it on your shoulders and do reps.  Or...pick it up off the floor do a rep ..take off your shoulders, drop it on the floor..  do it again.  Bench press...you cant do it with a bag. Triceps, cant do it with bag...not successfully anyway.  I enjoy the bag because it gives me a overall workout.  I do combine it with body weight exercises.  The one thing I have noticed, plates bulk you up.  Sandbags combined with body weight exercise, makes you leaner. Its my story and I'm sticking to it...LOL.  There are a number of videos which show a some great exercises one can do with the bag.  Hope this helps and have fun.

**Q: How much sand do i buy for the medium bag 26-75 to fill up completely?**
A: For the guy who commented below about the sand being pulverized, all you need to do is buy a liner for your sandbag. This will completely illuminate any issues you may have with sand just close off the liner with a heavy duty zip tie or a metal clamp that you use for a washing machine hose. Then place it in the sun bad and you won’t have any dust or sand coming out of it whatsoever. What you put in stays in!!!!!!!

**Q: What is the lightest start weight for the xl bag? how many filler bags does it come with?**
A: 20lbs

**Q: Does the Camo M option come with any inner sandbags?**
A: Yes they come with a 50lb and 25lb inner bags

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality rugged and robust
*by G***M on 31 August 2025*

Been using this for over a year now and it’s been given a beating and it’s held up very well, good quality and very robust.

### ⭐ Disappointing
*by A***R on 25 January 2025*

If the inner sandbags are filled to capacity, they don't fit inside the outer bag. If the inner bags aren't filled to capacity they move around too much, changing the distribution of the weight.The stitching is poor quality. When filled to capacity you can hear the stitching snapping. It is unlikely to last being thrown around during a workout. Not fit for purpose.

### ⭐ Already damaged
*by D***M on 4 January 2024*

I was looking forward to using this product as I often work in very remote areas and rarely have access to a full gymReceived the product, used it frequently and all was goodThen yesterday one of the filler bags split. I've had the product for less than 2 weeks.
