This fits more during a power/peaking phase. There is a band version that Cal Dietz (Triphasic Training book) has documented in his youtube channel that is pretty much the same thing.
With injury prevention, I have begun to see programming over several years in that you want to spend as much time as possible doing the “boring” stuff like eccentric ham curls and strength focused programs before considering adding funky things such as this hamstring kick variation because once the season starts you will be doing lots high intensity running.
Again, that’s a nice variation you’ve picked up. With programming, I’ll be reserved with volume and have it done during a power/peaking phase. Assuming everything else is covered and your hamstring strength is good.
