Sounds like a crossdressing issue
Ok, let me give you guys a little more info.
I also workout at the gym 5 times a week, legs once a week and use the stationary bike nearly every time I visit for about 20min at a resistance of 13 out of 20. 20 being max.
Last june I had ACL replacment surgery and my leg shrunk a couple inches. But I've been rehabing since day one after the surgery. Just about back to normal. Whatever that is
Yet I can hike up Si in 70-80min packing light (very light)without much of a problem.
Just don't get it........
