Firstly, I would not do the same HI intensity workout three times a week. If you want to do 3 HI days, I’d go for something like
Day 1: acceleration (i.e. block starts to 30m, but progressively getting longer, maybe with a single 120m run at the end) total volume ca. 300m
Day 2: top speed (e.g. flying sprints, EFE, FEF) total volume ca. 350m
Day 3: SE (e.g. 150m, 200m - could do a couple of 30m accelerations before those) total volume ca. 400m
Using 2 HI days you could do something like:
Day 1: acceleration and speed
Day 2: acceleration and SE
For weights, I would not do any bodypart (except for abs maybe) more than 2 times per week. E.g. lower, upper+lower, upper or something like that.
