Ah ok. If it doesn't come with a barbell, then what you likely want is a 5ft barbell that weighs 25 lbs, with two inch sleeves on bushings (i.e., not a one piece barbell). Something like this may work:

I was going to order this, but then picked up a used Tempo barbell off of fb marketplace.
A regular olympic barbell is 7ft and 45 lbs, so I'm not sure that would work with the algorithm's expectations.
Here is a quick guide on how I fixed my tempo's bluetooth connection. My connection to over 6 different bluetooth headphones would drop out in front of the machine, the connection beside and behind the machine was fine. Tempo walked me through replacing the original antenna with another stick-on antenna under the shelf, but it still only fixed the connection while I was close to the machine, at the mat my sound kept cutting out still. So I replaced the second antenna with this one from Amazon https://www.amazon.com/gp/product/B08HM8NG7L/ and am now able to even leave the room and still get full sound on my headphones.
Technically this should also greatly improve wifi, however my wifi was already good to begin with so I did not notice an improvement.
