Interested in the answer. I don't compete in any sort of cycling fwiw, my athletic outlet is competitive Judo (welterweight Y/O/G senior) and TKD (welterweight black belt senior). I weigh in around 170lbs.
Right now I'm using Mark Rippetoe's method. 3x5, all barbell training and compound lifts. Squats (of course), deadlifts, bench press, OHP and power clean. Works excellently for me, I'm stronger than I've ever been and I still don't have any trouble with my weight classes.
I figured I'd get rec cyclists, competitive cyclists both on the road and in MTB and athletes from other sports here which is why I put it in Foo. I'm interested in whether you guys have embraced the barbell yet or not. I'd imagine most of the racers here feel a need for serious strength training but wouldn't be my first time being wrong.
