I recently started to train upstairs in my apartment (house is pre-WW1, so there’s little insulation and sound travels quite easily). I found an old NYCC post describing using GreenGlue in a “sandwich” of plywood. I built the platform, as described with:
- Trainer Mat or yoga mat (~$20)
- 6 pieces of 2’x4’ plywood, 1/2" thick (~$110)
- 2 tubes of GreenGlue (~$60)
- 100pk of 3/4" wood screws (~$8)
- Closed cell rubber sheet (~$50)
$250 seems like a lot, but I rent an apartment, I like my neighbors, and I prefer not to worry about the noise. Plus, when the wife and I buy a house, there’s no guarantee we’ll have a room where noise isn’t a concern. I just tested it today and it does an impressive job. I use an Elite Direto which while not the loudest trainer is not known for being particularly quiet; we could barely hear anything in the room directly below where I was set up. Our neighbor actually didn’t notice, we went down and asked to test it out.
