Has anyone used a reverse hyper extension chair for back pain or have a recommendation for a particular brand of the reverse hyper? I’m working myself back into shape after having lymphoma cancer in 2020 and then tried to come back too fast in 2021 where I chopped too much wood 🪵 and injured my back. I’ve been through physical therapy last year and it made a big difference. In the last 3 months I’ve been able to get back into light weight lifting and running on a tread mill. I still incorporate stretches from PT, but want to take it to the next level.
