Thought i'd finally contribute with some figures. Some are from last year, but over the next few weeks i'll be attempting some 1RM to clairfy.
Stats: 19, 5ft 10, 85 kilo. Waist 32", Chest 43".
Bench: 107.5 KG (last year, freeweight ofc)
Squat: 100 KG(Smith machine from last year)
And from yesterday after my 4th session of deadlifting, now having the correct technique, and owning some lifting straps...
Deadlift: 150 KG (straps)
A friend advised I stop at 140, but he wondered off to do some pec fly, so snuck another 5 and then 10 kilo on the bar. Lifted it about 5 times in total. Quite pleased with myself, and I dont seem to be aching at all for now! I can only assume if my back was not straight enough or form good enough, under those sorts of weights you can expect an injury if you're doing it incorrectly?
But there we go! I'll attempt a 1RM on squats sometime this week and post back, its not an exercise I bothered with much but having started training my legs over the last few weeks hopefully all 3 lifts will increase as I begin to grow properly.
