gripped's schedule, where you go alpine climbing on one day of the weekend and do nothing on the other, seems kinda weird. and by "rock climbing" I believe he means "gym climbing" cause what crag would you go to for only 2-4 hours?
On those occasions when I train I start off by planning that both weekend days will involve extertion of some sort whether it be slogging or cranking and go from there. Monday is usually a good rest day if you go all out both weekend days. Thinking this thru the rest of the week you can have Tue, Wed and Thur as more workout days and then on Friday either you go out and party or drive to your weekend objective, so its a rest day either way. Assuming you work that is. If you don't work, then just take bad weather days as training or rest days, and climb the rest of the time.
