A friend asked me to comment on this rapid-splits method. I was not exactly positive in my response.
See https://hyperbolicstretching.net/fullpower/
However, all is not lost, because I also found this in a website about the technique: "Alex Hyperbolic stretching is a flexibility fitness program that is specially designed for men who are looking to increase their male organ and perform to satisfaction in their responsibility as a man with their wives." Not only rapid splits, but you perform better in bed.
Does everything!
Anyone have any comments, or any experience with it (in terms of flexibility, at least)?
Jim.
