Let's continue where we left off in our PMs

"and yeah im prone to being fat, should i ditch the dairy even if im drinking no fat milk? @>@ ouh and i didnt mean cereal per se, meant oats and weet bix XD"

Being fat is not about eating fat. It's the excess carbs that is making u fat provided your caloric intake is within your range. Weet bix and oats are a great start for complex carbs source. Eat your veggies also.

I have posted a post on how to perform your 1st pullup and I am too lazy to search it. It involves performing negative pullups, the pullup machine has very little carry over to the real pullup. I say man up and give the bar some tuggin.

What are your goals again ?

Don't stand on the assisted pull up machine.
Kneel with the knees (and the feet off the ground) on the machine. Meaning only the knee touches the support, the shins, toes and feet is pointing upwards into the sky.
And look up at the ceiling above your head. (Imagine theres a piece of nice Belgian chocolate bar hanging from the ceiling, and then you to pull up and literally take a bite with your mouth). <--- seriously, it makes pull ups easier this way.

Then EXPLODE up! Don't just pull, EXPLODE!

Also do the 'negative pull ups' without assistance.

And do a bit of heavy pull downs (lat machine) too. I know it doesn't carry over (to pull ups). But since you're doing negative pull ups at the same time, the strength gained from it can be useful.
