I just finished stage 3, was in and out in about 50 min. I included a 5 min warm-up, but no cooldown. Plus, I only rested what I needed to, and never took the full prescribed rest time - I think I would have been in the gym 90 min if I had, and I just don't have the time for that, 3 days a week. I realize that by not resting, I'm giving up on some potential strength gains, but I'm still happy with my progress so far. Also, I rarely did the intervals right after the weight training, I either did them later in the day or the next day. You can play around with it, just remember if you make changes it's not the same program!
