Recommend a protein supplement?

CrazyJames, I meant in no way to offend you, but your tone - in response to my post was pretty fucking defensive.
This is a cycling forum, and my response was aimed at resistance training for cycling
Let me explain:
In a flexed cyling position - lets use the track for an example - your lats contribute to stability on the bike by drawing your arms into the body and to assist in sprinting. FACT. In this instance it is a core stabiliser.
and what the hell is a rotator muscle? if you're talking about the rotator cuffs then they in the shoulder area, quite far away from your "core"........
Are you aware of what medial rotation and lateral rotation is????? Well guess what - we have muscles in our legs that medially and laterally rotate the hip joint. You really did want to make me look stupid didn't you......

I'm suprised it took you extensive work to realise this/ Right idea but wrong explanation,
CrazyJames - i apologise if i offended any of your current training methods, but i aimed my advice at cyclists, and not powerlifters.
I was merely sharing my experiences of working within a neurological rehabillitation environment, and expressing my findings, which i have applied to exercise performance.

Apologies if my tone came across as defensive, it wasn't intended in that manner at all, and sorry if I was a bit arsey.
With regards to the discussion on lats, yes they stabilize your core whilst on a bike and during movements that is correct, but they are not by definition core stabilization muscles (excuse the extreme pedantry coming up):

The core or LPHC (lumbo-pelvic-hip complex) is made up of two categories of muscle groups.
**1) the stabilization system-inside muscle group and **
**2) the movement system-outside muscle group. **
**The stabilization system is responsible for the stability of the LPHC and includes the transverse abs, internal obliques, lumbar, pelvic muscles, diaphragm. **
The movement system consist of the lats, hamstrings, hip adductors, hip abductors, rectus absominus, and external obliques.

You referred to them as core stabilizers which they are not, as they are not directly involved in stabilizing the core in all instances which is what defines a core stabilization muscle, independent of whatever movement/exercise is taking place, this applys to any exercise, not just cycling/powerlifting.
I'm aware of what medial and lateral rotation is, fairplay I was an arse in responding to that, just a lot of people try and bullshit about that kind of stuff which annoys me, its clear that wasn't your intention now so I apologize.
You didn't offend me, I clearly just made some incorrect assumptions about what you meant which lead to behave like a bit of an arse, sorry if I offended you.
I'd be very interested to hear about your workings in a neurological rehabilitation enviroment, as I suffered massive nerve damage in one of my legs quite a while ago which still affects me from time to time.
