Keith, these workouts can get on the long side. Mondays, Wednesdays, and Saturdays are all over an hour.
Part of the reason is because I will work up to a heavy single in the lifts, drop and work back up again in an attempt to build consistency and push my max for the day--I don't know if that's what was intended in the programming.
Another part is that I DO sit down during workouts, and try to rest for my next heavy set when I feel I need to. I think this not only increases the time of my workouts, but it also helps me push my maximum weights for the day. On the other hand, I'm sure I'm losing some sort of conditioning aspect that would be gained by not sitting and resting a little less.
