need some advice on my training plan (newb alert)

hi everyone, i been going to the gym every once in awhile (about 7months)  and it's only recently that i draft up a workout plan and been following it for 6 weeks going 7th now. However, it seems that recently, i dont feel as much ache anymore.

I'm assuming that it is because i am building resistance to the excercises i am doing. And probably my planning will need some tweaking too, considering i simply mapped it out without any experience.

any help and advice will be most appreciated.
