Anyone have an issue with rubber legs early season? I didnt have this issue nearly as bad last year. Not sure what's up, maybe age or arthritis getting worse - but my legs are burning and getting tired pretty quick. I do some exercise off season but probably not enough. After 3 hours of solid riding (much of that lift time), I'm pretty wobbly and only good for light riding thereafter; otherwise, I'm a danger to myself.
Someone in here recommended squats, and holding a squat to build up leg stamina, but due to my knees getting bad, that's a lot of stress to put on the knees.
I'm wondering if anyone has any magical tricks like, standing on your toes or, holding onto a door while leaning back or something that they know works to build up leg stamina similar to what is needed for riding.
