Doing 10 reps MS style is "less efficient" then doing the same 10 reps with the same weight straight. Being able to do 20 reps MS-style with your 10RM, now that's when MaxStim makes sense. Please, correct me if I am wrong.</div>
I described the problem I had with MS earlier in this discussion, I think around June 2008. I had a big problem with DL. Seems the volume was too much. So I thought to reduce the volume for DL only.</div>
I reckon deads have to be treated a little differently to most other exercises when performed MS style. The holistic nature of deads makes them an extremely taxing exercise when performed with a heavy load (ie. 90% 1RM and above).
A 'proper' deadlift session is pretty much MS style anyway as you are performing each rep individually from a dead stop, with a bit of time to set-up between reps (even if it's very short). As such, trying to get 20 reps with your 5RM (or higher) for deads on a weekly basis is probably going to be too much for the average seasoned lifter - folks new to lifting might cope quite well for a while.
But what about using a 10RM load? Surely, that would be fine for 20 MS reps? Well, I think that depends on how you found your 10RM. If you completed a set of 10 'touch-and-go' deads with a certain load that you then called your 10RM, expecting to get 20 MS reps with that same load might be a bit of a shock. Each MS rep is going to be more taxing than any of the touch-and-go reps, barring the initial one (because of stretch reflex, bounce off floor that you get with 'touch-and-go' reps). It would be better to find your 10RM by finding a load that allowed you to do 10 consecutive singles, with just time for a breath or two and a reset between reps.
Perhaps a better way to approach MS deads would be to start with a load you know you can handle for 20 reps with an M-time of, initially, just a few seconds. Then, each deadlift session, increase the load by 5-10 pounds (or whatever increments make sense for your cycle) and go for your 20 reps - increasing M-time as necessary to keep fatigue at bay.
Once you reach a load where an M-time of 30s is required early on in order to complete all 20 reps, you are probably pushing yourself pretty darn hard and in danger of frying your CNS. That may well prove to be heavy enough for your cycle but, if not, then in order to continue to increase the load, I think it would be prudent to lower the total MS reps required from 20 to, say, 15 and then from 15 to, say, 10. You could always add some lighter reps if you wanted to increase the total work done.
Don't forget that, for conventional deadlift reps, it is usually not necessary to do more than one or perhaps two heavy work sets of 5. Ripp suggests just one heavy work set of 5, after a succession of warm-up sets, in order for a decent amount of overload to occur. In my case, once I am close to my 5RM load, I'll aim for a total of around 10-15 reps (I will only do a single set of 5 but I may well follow that with clusters of triples, doubles or singles). I have yet to try 20 MS reps with my 5RM for deads so I don't know how much less taxing that will turn out to be. I'll have to give it a shot sometime soon.
