Where I'm on the edge of "blowing up" while pulling the line until I need to rotate to the back.
I ride with a group where most guys are stronger than I am.
It's not uncommon for me to average 170bpm on a group ride.
You're not "blowing up." If you were "blowing up" you'd fall off the back and have nothing left to catch up. You don't know what riding hard is, as most non-professional/collegiate athletes know. You've never ridden hard enough to experience "hitting the wall."
A hard workout will leave you with nothing left. You will barely be able to make it home. The next day is your recovery day because you physically can't run/bike any faster.
You're not working hard enough.
My guess is the OP is overweight and losing weight, therefore getting constantly "better" from loss of weight/gaining muscle.
