Thank you for your reply.
I will make another video where im lifting a much harder lift, i'll make it next time i do deadlifts.
I know what you mean about the bouncing, the first pull is always the hardest, ill drop back my working weight a little and reset each rep.
I'll grab a mat to stand on, because i'm doing this in my own house at this point and the floors are wood i really need the mats to stop dmg.
Chalk maybe hard, as it could make a bit of mess in side, ill lift with out straps until i cant grip anymore then use the straps for the last few sets, instead of using them from set one.
Competing isn't in my current list of goals, i asked for advice in the power lifting section because power lifters know what a dead lift is supposed to be. I don't want to destroy my back :D.
After i hit my weight lose goals i will be joining the local gym as a reward. Its a gym where i can lift properly, rubber floors, plenty of racks rubber coated plates etc.
