I am def going to say ur working out way to much,also you are doing 1 hr of cardio which is well over what you should be doing.I will give u my workout and u should try it and see how it works for you.
3 day burn i lost 25lbs in 2 months eating junk food
something you should not take from me at all. Yes i ate like a pig and still lost,But the results to a flat stomach and abs will come with eating right.
sunday night
* 5 min bike ride before back and biceps followed up with a 12 min back ride and 75 crunches
tue night
* 5 min bike ride before shoulders and legs followed up with 12min bike ride
thur night
*5min bike ride before chest and triceps then follwed up with 12 min bike ride 75 crunches
If you wanted to work 2 more day's of gym in,Use those day's for abs and no more than 25min cardio.I must say for best results stay off these 4 things:sugar,fried food,high carb foods,high sodium foods. And try to drink no less than a gallon of water a day
P.S remember anything over 25min of cardio u just burning muscle and you dont want to do that because muscle helps burn fat
