Need An Outisde Opinion

[MichaelDawson18]

I'm 15 and over the past few weeks i've started to do nightly workouts, nothing extreme as I don't have a gym membership I was wondering if anyone had any advice of ways to improve or other exercises I can add to my repertoire in order to get bigger arms and start to tone my ab muscles.
At the moment my routine looks somewhat like:-
-150 push ups w/ a heavy weighted backpack (doing reps of 10 with short breaks in between due to the weight of the backpack)
-150 sit ups (reps of 20/30 with short breaks (10 to 15 seconds))
-Leg lifts (Mix of reps of moving up and down as well as a simple leg raise and hold for as long as possible)
-Planks until I drop (in proper form this varies between 1 minute and 1 and a half)
Obviously these are fairly unexceptional results but i'm just getting started and any help would be greatly appreciated. I have a clean diet and drink lots of water as well as play basketball frequently in intense games. I do this "workout" 5/6 days a week.
Really any help would be greatly appreciated, don't have any access to gym equipment yet.
Thanks in advance.
