Got this for lifting and CrossFit WODs for my wife and I. Solid. Bolted to a 2x12 stringer board to wall and 3/4" plywood underneath sitting on top of carpet. Amazing can do kipping pull ups, Toes to bar, ring rows, knee raises would need a hole in the ceiling for muscle ups, but this rack could definitely handle it. The j hooks are solid and glad I went with the 3x3 steel. Only 18" from wall perfect for our small space. Didn't need the extra side bars for bracing below.
