Just joined a new gym owned by a former MR Universe, he told me he never does a warm up or stretch before a workout ......... also watched him train and he starts with heavy weight first then drops the weight and increases the reps.

Never heard of anyone doing this but the guys a monster and in his 50s....

That is quite unusual and I wouldn't recommend it. He is lucky if he can go straight heavy and remain injury free. It is always advisable to get some blood into the area you are training before maximising load.
I would suggest that a couple of warm up sets would be the way to go, for safety's sake.

i went too heavy too soon one winter in our breezy old mill gym on a shoulder routine and paid the price with a damaged rotator, my advice is always do a high rep light weight warm up  ;)

yes its called drop sets it is a advaned training method it is very good you should try it some time,

I nearly always do triple drop sets, but not before doing a hi rep , to failure, warm up set to get some blood in the area. Any physio will tell you that to go straight heavy, with no stretching or warm up sets, is asking for trouble.

Yes, a good example are lateral raises, i do 2 warm up sets say 25lb and then run the rack from 50lb down to 15lb db's, just for extra torture follow straight in with some 50lb 'burns'. Lovely!!

u should never streach a cold muscle.  streaching is not walming up. nor is lifting light weights.

walming up is getting more than "that is at rest" amount of blood in to a dissired musle, or muscle group.

walking briskly up the stairs to the gym is enough to prep the legs for streaching. just as long as u dont train on the ground floor!

this guy might not do a set walmup but im sure he has a routine weather it is flexing in frount of the mirror in the changing room(most peoples favirot) or running from the car to the gym.

I see your point, but I can't go into a gym and leg press top weights without flushing some blood through first with lighter sets, regardless of if I do cardio or not. It hurts my knees too much. If I do what I consider to be a warm up set or two, then I don't get the pain in the joints. Horses for courses, it works for me.
