Hi. I’m sure I am not the only one who gets lots of training ads based on using sites like sufferfest/systm and others. Does anyone have any experience of using things like airofit breath traininers? The data seems sketchy. Obviously they sell pretty well but I wonder if it is a gimmick and using the yoga and other non bike training might be a better idea.
What do people think? For background, I did have childhood asthma but not needed any inhalers for years. So no real respiratory health problems
