I think you could satisfy all of your needs with an RDL or glute-ham raise. I’m not completely opposed to leg curls I am just of the belief that if you can accomplish a task using free weights or bodyweight + any needed external weight as in a GHR (which I like to think of in terms of being a lower body pull-up), that is the way to go.
Further on leg curls I don’t know how much they really contribute to hamstring mass as there are many athletes who have superior hamstring development from sprinting and multi-joint exercises that a large degree of hamstring contribution to the execution of the lifts. I’ve never found the leg curl to be necessary in the training of any athlete I’ve ever seen. That is, I think there are better tools for accomplishing the goal of hypertrophy of the hams than leg curls.
I like your order for the clean pulls, gm and bench. I could see an argument for splitting up the total body exercises like the cp and gm with the bp but I prefer the order you have listed.
On the circuit, I’d just say to be very careful to not let intensities creep into too high of a range so as to not compromise the high days and those exercises even though I’d prefer not to do the circuit in the first place.
With regards to ordering I’d think 1)ss 2)chins 3)db mil press 4)leg curls might be best though I could see an argument to be made for switching 3 and 4 to split up the lower and the upper work. On the chins again, I think they should come fairly early since being a bit more fatigued can really compromise gettting the reps you might be seeking.
I only asked about the other exercises to see if you really are only lifting then perhaps more volume is necessary if that is your only means. How much volume are you talking about with regards to the sprinting? Any plyos or med ball throws?
