wanna do 5x5, don't know which one

[snyper99]

So was reading the stronglifts book and he says to start with the bar so u can keep adding weight every day

i start with the bar for the first set of warmups only and work my way up according to the spreadsheet/calculator

 

[Mr Mob]

start with 70% of your max

if you're new to this type of training/routine then youtube mark rippetoe....you won't find better tutorials, I started a 5x5 program that Zed set up for me last week and right now I'm really focusing on technique with lighter weight before I start my cycle so I can really dial in the routine...technique is everything on compound lifts

So when I start my 5x5 program I should start with 50% of my lifts ? And build it up 2.5 kg next time and so on ?
