When will I start to notice results with my workouts?

i do abs/legs 4 days a week and arms/butt/back 3 days a week! I've been doing it for about 2 weeks straight… and i do 3 minutes of planking, 3 minutes of low-to-high planking, 3 minutes of flutter kicks, 3 minutes of side crunches, 3 minutes of heel touches, 50-60leg lifts, 200 bicycle crunches, 3 minutes of squatting, 3 minutes of scissor kicks, 3 minutes of lunging 2 minutes of wall sits, 3 minutes of plie squats, 3 minutes of pushups… and some arms stuff! I'm already skinny.. but trying to gain a little bit of weight! any idea when i should start to notice results? thanks
