van, so can is it ok if i do cardio for 15 min, workout 15 min, thn cardio 15 and workout 15? my goal is to get rid of fat on my tummy, thigh, and arms, while gaining muscles on arm, chest, and some packs on tummy.

my routine is as follow:
morning
push ups 20 times/ set, for 2 set.
leg lift 50 times
dumbbell lifting 30 times/set
flat dumbbell fly 25times /set
sit ups for as much as i can
it goes push ups> leg lift > dumbbell> fly > sit ups > push ups

rest on noon

evening
walk/jog for 15 mins
get on the equipment for chest press (i dunno wat ppl call it, it looks like a bike without a wheel where u work yr chest n arm muscles)
dumbbell lift til max
sit ups
bike cycling for 15 min
push ups
bar bell lift
chest press
walk/jog back home for 10 min..

i only eat after workout, so my stomach is nearly empty before i exercise.
can i build muscle n lessen fat tat way?

btw, my height is 1.77m, weight around 62kg. skinny type with small bone n narrow shoulder, big tummy.
thanks for advice.
