5 of 5 Worth every penny March 23, 2020
Reviewer: Jaime Rodriguez from Royal Oak, MI United States  
I’ve been on my board now for a few months. It’s still fun and challenging. I just love it more and more. 20 minutes carving around the living room carpet while listening to The Beach Boys and I can barely stand up. I thought after I bought the 8.5” ball I would get bored with the 5” balls, but there are still all kinds of combinations to challenge. I’m saving up for a bigger board. I’m so glad I found Si-boards. The quality is tip top.

5 of 5 Excellent product, the BEST medicine balls! June 19, 2014
Reviewer: Evan Klaus from Glendora, CA United States  
Every Si medicine ball is extremely durable and stands up to abuse very well, and I predict that these balls will last for many, many years of wall slams, etc.

This 8.5" ball is excellent for two armed throws, sagital-plane abdominal work (i.e. granny tosses), & transverse-plane abdominal work (i.e. rotating tosses). I've never enjoyed doing abdominal-core workouts before, but throwing this large Si ball around turns ab workouts into a fun game. I've definitely noticed greatly improved stability in my whole torso while doing Front Squats after training with this large ball. When I Front Squat, I feel much less like the bar is able to pull me forward.

I will be using these medicine balls for years to come, and I am so satisfied with the purchase I would happily buy a replacement pair several years down the line if they do end up deteriorating -- so far, though, I predict that these products will last AT LEAST 5 years, and quite frankly, I imagine they will last longer than that.
