I got a recent question about what would be the best pullup rig for someone who was going to be using it on a cement floor where they couldn’t anchor the rig. This person wanted a rig that would not move when doing butterfly pullups and would have a high enough anchor point for rings. He and his wife would both be using the rig.
The height of the S3 would allow him to hang rings, while also having a lower pullup bar that both he and his wife could use. loading his plates on the base storage, would keep the rig stable when kipping or doing butterfly pullups without having to anchor the rig to the ground. The video above shows how stable the S3 can be, even when not anchored to the ground.
