by hiking do you mean walking up a hill? why walk when you could jog or run... just my opinion.

Here's what my trainer has me doing and I feel it works me pretty hard... Monday, Wednesday and Friday I jog 3 miles. Tuesday, Thursday and Saturday I alternate 2 minutes of hard running with 1 minute of jogging for a break, it sort of simulates fighting a round and then having that break between. The best Ive done is three rounds.

opinions, suggestions? what does everybody think of that for conditioning?
