All I know is what is on this site. I know that MVP does sleds once a week and short hills once a week. The sleds are supposed to be up to 50 pounds for men and half that for women. The short hills are 10X40m up a hill that is supposed to be 40-45 degrees. This is from the seminar notes from Australia last year that have been posted.
I don’t have a sled but have a similar hill, so I did the hill workout once or twice a week.
I don’t have any details about Bauman’s or Mills’ sleds.
