Absolutely no muscle strength on attacks
This is one of my weaknesses by a longshot. I think I have pretty decent aerobic capacity. I always ride flats atleast at 100rpm, anything lower just feels too slow. But the thing is after sprinting on flats, especially sprinting up a little climb or sprinting right at the top of a decently long climb (1-2mi is the longest climbs around here), I am absolutely done. My legs just feel extremely tired, then my heart rate sky rockets after sprinting, and I must take it down a notch, or two...or 10. I lose all my speed. The good thing is my heart rate drops extremely quickly after raising it but for 50-60sec after sprinting, i am wiped out
I think this has to do with weak leg strength, as I always spin on flats and if it is anything below 90 my legs feel like they are "really trying hard"
