: Ensure there is a small amount of "free play" in these arms; over-tightening can cause friction and make the exercise feel jerky. 5. Finishing Touches

Mount the main vertical support post (the "backbone" of the machine) to the center of the base. Screwdrivers : Phillips head
: Use Allen wrench bolts on the top bar to pull the vertical poles into the final correct position. Once these are tightened, the main frame is structurally sound and you can go back to fully tighten the base bolts. 4. Dynamic Arm Attachments
Before you open any boxes, read these safety rules. Incorrect assembly of a cable pulley system can lead to sudden cable failure or injury.
Still, the machine’s mechanical heart retained traces of its origin: the assembly instructions that had called it into being. On long nights, Mara would take the manual to bed and read the diagrams like constellations. She found notes penciled in the margins—not by her, she was sure—tiny heuristics about turning torque just so, about the optimal pressure for the wheel casings. Whoever had written them had a hand steady enough to trust and a humor that echoed the machine’s small courtesies.
