Jasperina, I use the vibration plate in the Total Body Enhancement Machine at Planet Fitness. I am 70, so regular membership is free with Silver Sneakers. I give them 14$ a month for Black Card to use the hydromassage, and vibration plate. The machine is a "Beauty Angel" and has red light therapy, which I am not interested in, so I keep my clothes on and wear dark glasses. I used the plate at the Beginner (five minutes and quite gentle) level for a couple weeks and then tried the Intermediate (8 minutes and a bit more aggressive for part of the time), which they say is suitable for beginners as well. I don't intend to go further, unless my BMD density improves to an Osteopenia level. For some this might be a stretch, but I feel really comfortable with it. I think the quality of the plate matters, and from what I have read, this is a decent one. I think it's a personal call, and consulting you doc or trainer is always useful. There is a YouTube Tutorail if you are interested: https://www.youtube.com/watch?v=zV7uNluSBgA
