No, really, it does. It depends on your standard of fitness, on how old you are, on how big an aerobic base you have, on how intense and hard your intense and hard days are.
But however fit you are, and however big a base you have, I can't remember seeing any coach or training manual recommend intense interval sessions on successive days, at least not on a regular basis. As a weight lifter you'll know that you break muscle down while lifting, and build it at rest. Cycling is similar in that respect. You get fitter as you recover and compensate for the effort.
im 25. great shape. great diet. taking aminos, beta alinine, and aakg (nitric oxide).
I usually mix a single week with (in no particular order):
*2 day* intense intervals 2 mins hard 4 mins rest for 8 sets and then finish my ride at an enjoyable casual pace. anywhere from 15-30 miles.
*2 days* 8 mile hill climbing route. I go as fast and hard as I can the whole time.
*1 day* aprox 50+ miles tour.
any remaining times in the week I rest or I ride are just for casual, easy, or with my family (pulling a trailer at low speeds).
