Josh, thanks for the feedback.
I realize the two goals are polar opposites of each other, but now that I am dropping swimming and biking from my training, I thought (probably naively) I could step up my lifting just a tad. My schedule over the summer included lifting only on Mondays and Thursdays, where I would do power cleans, squat, and shoulder press on Mondays and power snatches, deadlift, and bench press on Thursdays. Pullups were also thrown in on either of those days. I basically maintained my strength on SQ & DL by using a variety of set/rep schemes, including dynamic efforts.
I guess regardless of whether LP plus endurance training is not a good idea or not, I still have the question of whether LP using 3x3 in lieu of 3x5 can be just as effective in gaining strength.
