Another way to go would be…
w1 3x3x50 2min
w2 3x3x50 90"
w3 3x3x60 2min
w4 3x3x60 90"
w5 3x3x60 1min
w6 3x3x70 2min
w7 3x3x70 90"
w8 3x3x70 1'
w9 3x3x80 2min
w10 3x3x80 90"
w11 3x3x80 90"
w12 3x3x80 1minI think that works better, considering the comments made my mike and ut. That way the volume and intensity aren't jumping up too much too soon.
Thoughts.
As I said I don't have any experience with this kind of training but i could imagine it being a hard progression.
The 3x3x80@1' rest seems tough considering a pace of 90-95%. Than again I'm kind of lazy and just don't like those hard workouts 😛
I really like the 1'-2'-90" progression to bridge the distance leap though : )
