I find that my cycling endurance is excellent on a generally LC diet IF a.) I do not allow myself to become exhausted (like climb hills too aggressively) because recovery is difficult, and b.) if I eat carbs WHILE riding. No pre ride carb loading is needed, and I eat far fewer calories worth of carbs than I typically expend. As a profuse sweater (off the crown of my head usually) hydration and electrolyte balance is my bigger maint item on long rides.

For my calisthenic workouts, LC affects me not at all. I am making steady gains on sit, push, chin and pull ups. Almost back to where I was during high school or basic training PT test days in the early 70s.
