@Gobacktotheworld thanks for the Julia Reppel link. I do a bit of running so will take a look at it. Today I did a Legs one from Iron Pro and that did make more sense as she increased her weights with each round and went heavier than I have seen her go. There was one odd part of the workout though - 3 sets of bodyweight step ups. They felt like a bit of a time waster!
I think Iron Pro would be a good programme for beginners or people coming back from illness with the 45 mins of effort and 60 secs of rest, obvs with "normal" weights and not trying to go really heavy.
