I'm weak as shit. what can I do?

Basically, i have read all the stickies through and i cant find anything relating to this, I've recently started going to the gym, and i struggle to even lift the smallest weight they have, which is 8kg, I attempt to do 5 sets of 10 reps each time but after the first 2 sets i struggle to even lift the weight at all, im extremely weak when it comes to weights and i guess i just want to be assured this will even benefit me.

TL;DR New to the gym, struggle with weights, do cardio and want to lose weight, i only go once a week because of my student wage, what do?

>Pic related (not me), am average size 5ft 7 male, weak as shit though,

Start with bodyweight training

then do 3 sets of 5, fucktard.

Currently im doing
3 sets of 5 on the bench bar (45kg)
5 sets of 10 reps with free weights
and 30 mins on a treadmill
tryna lose weight and tone a little but i only do this once a week, will that even do anything? ^

I'm like 11st 8

Alight then, behind the fucktard that's actually decent advice, so cheers.

I'm literally a complete newcomer.

It will probably do something but you must get on a real program, did you really read the sticky?

I did yeah, but as I'm literally new as shit, to the gym I'm at, I'm still working out where everything is and that, and I'm waiting for my friend to come with me so I don't end up killing myself doing squats and that, as i said i'm REALLY weak, to the extend i doubt i could even lift the bar for a deadlift or squats so i'm a bit comprehensive on doing it

Also the 3 i saw require 3 days a week, and i can only do one day (or two if im lucky) a week besides home exercizes

Do push ups bodyweight rows and bodyweight squats 3-5 sets 5-12 reps each every other day for a month or 2 if you are having trouble with the raw bar i would say.

Thank you, ill try that out and post results in a couple of weeks, appreciate it alot user.
