Cool to hear you liked that tip too. It may be all I need, we'll see. Once I hit seven miles (which is a nice run to, around, and back from a lake near my house), I will be running a little over an hour per outing. I will set that as my max time and then focus on running faster, eventually increasing mileage in order to keep the total running at about an hour. As I increase velocity, I will try to incorporate the knee drive more and more and see if that feels sufficient. With all the opinions out there, I don't know if we really have any choice but to experiment, read up a bit, participate in these forums, but ultimately trust our own bodies' reactions and proprioception. I did just buy Ken Bob's book however, and will look through it for new ideas. I'm impressed with the quality of the printing. I only wish I could remember how I ran barefoot 20 years ago, while in Japan, back when I didn't think about it. At the time I didn't even know I was BFR; I was just training for karate.
Anyway, keep your posts coming! And thanks for the link--I'll have to look over that site more when I have some free time.
