This unit is absolutely amazing. It took me 2 days to put it together by myself. I would recommend having a helper to hold things in place during construction. Directions were good enough to get it done. Working out with this Mikolo Smith Machine Home Gym, 2200LBS Power Rack with 36pcs Aluminum Pulley, Functional Trainer with Dual 132LBS Weight stacks has truly upped my game for work outs. I am 67 years old and loving this system. I am fairly new to working out, only a year in. This unit was an upgrade for me, and I could not be happier. Well worth every penny. I do highly recommend this unit
