Payment & Security
I purchased the 3-person worm several weeks ago and it’s super quality. I received daily direct messages from the company during the shipping process and received the worm within a couple days. I’m beyond thrilled with NSG and from here on out, I will buy all my gym equipment from them. I highly recommend Never Stop Grindin! 👊
Purchased this worm a couple months ago for my gym and I. Things have been great since day 1. We have used it for thrusters, walking lunges, push press and clean and jerks. Its high quality just like the sandbags. If I had to buy another one I would not hesitate to buy from NSG again!
