I’m concerned with the jumps. They are of a highly advanced nature: depth jump, single leg stuff. Since you’re a beginner focus on double leg jumps in the ‘up’-mode, i.e. jump onto a platform, and later progress to hurdle jumps in low volume at first (4x3) and always with perfect technique (i.e. short contact time).
Very easy to get injured otherwise, which would be totally unnecessary.
And as a 400m runner you could also do less jumps and introduce >45s skippings, in essence also a type of plyometric, for strength endurance
