400m S-L questions

F.e. the actual workout for the very first monday looks like this?

4X10
4X20
4X20 blocks
4x60 (20E/20F/20E)

4X60
2.5’ rest

For some sessions the volume seems huge, for example:

4X30
4X30 blocks
4x60 (7’ rest)
4x60 (20E/20F/20E)


You excuse I wanted to know the recovery among the 30 tests and then among the easy fast
thanks thousand
