# Step 4: Modify the lever system
We found that, initially, this lever is positioned rather high for using it multiple times throughout the day. If seeking a rigorous exercise routine, it may be left as initially configured. However, we preferred a more convenient setup for continual use, and discovered that reversing the arm that integrates with the lever works exceptionally well.

We drilled an additional hole in the rod extending from the base, as well as corresponding holes in the arm that attaches. This allowed us to insert an M8 bolt (5/16 inch) to securely fasten it in place. The supplementary bolt behind the arm prevents it from pivoting excessively, ensuring a stable footing.

You might consider designing an alternative system that enhances ergonomic functionality or visual appeal. Feel free to innovate!
