Three or four sets, 4-5 times a week? I'm not into high-maintenance relationships. Otherwise, a lot of what he says makes sense, but I don't know about the "tibial raises."
He typically has some good suggestions. Don't know about the tibial work myself, but I do think that the calf needs a lot more work to grow than other muscles. A low frequency guy like yourself might just throw in a couple calf day only in addition to working them on your regular routine.
I don't think so. But I do think I'll keep doing them once a week. I imagine that they get somewhat addressed when I do upper legs, and when I do my bodyweight squats for cardio. But the principal reason for keeping them is range of motion, which I referred to in an earlier thread:
Then you will fail to achieve the impressive gains I have made. It's a good 1/16 of an inch, maybe 3/32. Yuuuge.
