If Hydrow feels loose or wobbles too much with your movements while rowing, Try tightening the connection to the front legs:
First locate and check the four bolts which attach the front legs. It can be helpful to prop hydrow up either with the block the original packaging (as shown) or some other strong stable object to test for any wiggle or looseness in the feet.
You can then use a 6mm hex wrench to tighten these bolts down if needed. (one of these came in the box with Hydrow originally)
This process is part of regular cleaning and maintenance we suggest for Hydrow. For more, see How to Clean and Care for Hydrow
